World: r3wp

... and yes, it might be the problem of Windows, because how is that 
iPhone has relatively slower HW, yet feels speedier?

A lot of that is UI design.

speaking of which... iPhone OS 3.0 was just released.

'round being now a native. This should be welcome by those doing 
looped math operation.

10 times faster, more accurate, less exceptions

Yay! I haven't been able to review the ROUND and RANDOM tickets since 
the functions were being rewritten - this should help.

After reviewing the current state of the R3 module system, here is 
the state of what is implemented so far:
- Dependencies
- Encapsulation
- Explicit exports to the system exports
- Implicit import of the system exports

And here is what is not implemented so far:

- Explicit imports, even just limiting imported words to those in 
the dependencies

- Distinguishing exports for explicit import from the system exports
- Access controls for the system exports


It will not be possible to implement what is not currently implemented 
until the mezzanines and natives are put into modules. However, what 
is implemented so far is enough to start the process of putting the 
system code into modules. Further work on the module system (except 
bug fixes) and any preprocessor will have to wait until the system 
code modularization is done.

Regarding MATH stuff.I alway need functions to convert from scientific 
to human readable form including thousand seperators, using "," instead 
of "." etc. How about adding this to the CORE? IMO a very high frequent 
function.

Gabriele's FORM-DECIMAL function has always worked solidly for me. 
It could be considered as a mezz.

Yes, but making it native might be a good idea. I call this function 
a lot and with a lot of numbers while filling input-forms.

as long as it's not too complex. form-decimal is a rather complex 
mezzanine.

can't download new alpha, tried xy times and still receiving timeouts 
....

It's possible to download it from web using browser (but it's slow).. 
or try to enhance this value: system/schemes/http/spec/timeout

Downloads are here http://www.rebol.com/r3/downloads.html

maybe a better name would be numerize.

Specific formatting is always a bit of a problem, because everyone 
needs it, they need it to be fast, they need it to be consistent, 
and they need it to be completely different from what other people 
need. Personal preferences, industry standards, local standards, 
none agree. Fortunately in R3 native doesn't have to mean built-in 
or standardized.

Remember, "human-readable" depends on the human doing the reading.

Some notes on my first attempts to run R3-alpha against existing, 
published R2 scripts:
   http://www.rebol.org/art-display-article.r?article=j26z

Hmmm...

we don't use anymore "to-pair reduce [x y]" since a while, but "as-pair 
x y".

The script was written back in 2003, when as-pair was not availabe.


Oddly, R3-a58 does support to-pair, but not for integers, suggesting 
the problem is just a glitch:
    >> to-pair [1 2]
    ** Script error: cannot MAKE/TO pair! from: [1 2]
    >> to-pair [1.0 2.0]
    == 1x2

Interesting conversion in R3.
>>to-pair 2.8
==2x2

That's an R2 feature too. It kind of makes sense:
    to-pair 2
    == 2x2    ;; duplicates the 2 to create the missing value
    to-pair 2.8
    == 2x2   coerce to integer!, then as above.

to-pair [1 2] not working is a bug, btw. Has a ticket and everything.

pairs are very usefull in R2 I hope their functionality doesn't change.

Aside from that bug, I've seen no changes. AS-PAIR might go native 
though.

so when will the plugin interface be documented?

It's not even done yet. After this month I guess.

I just can't wait  :-)

is binary a string?
Carl wants opinions to help him decide:
http://www.rebol.net/r3blogs/0209.html

No twitter or other announcement, but alpha 58 is out -- over 25 
curecode issues addressed:

http://www.rebol.net/wiki/R3_Releases#View.exe_2.100.58_21-June-2009

yeah, I am really satisfied with last few months of developments, 
and I think that the community in overall is, as Carl is doing mostly 
Core stuff, and not GUI. R3 is getting more and more robust and consistent, 
although there is still some way to go. I can feel that we are getting 
more R3 fixes per month, than we get for R2 in last decade :-)

Yes -- I am hitting bugs, reporting them on curecode and often seeing 
them fixed in just a few days. It's a good time to be evaluating 
R3.

New operator !== for STRICT-NOT-EQUAL? - that was the last comparison 
action without an operator :)

Carl asked: wouldn't it be best to have same? to check for bit-by-bit 
equality? - this would "doom" same? :a 'a to yield False, requaring 
a new comparison operator to compare for "the same variable" case

requiring, sorry

So SAME? is less strict than STRICT-EQUAL? for words?

not just for words, for numbers,...

but, certainly not "completely less strict":

>> same? 'a use [a] ['a]
== false

>> strict-equal? 'a use [a] ['a]
== true

Weird - I thought it was a strict hierarchy of increasing equality. 
Never wrote code that would be tripped up by that.

new comparison operator
 - why not = or EQUAL?

this hierarchy never existed, AFAICT.

since equal? 'a use [a] ['a] should yield True IMO

The only thing I am sure about is, that the IDENTICAL? function ( 
http://www.rebol.net/wiki/Identity) is the finest possible (except 
for my bugs).

For SAME? I am more concerned about word binding equality than datatype 
equality. If the datatypes differing would make the return value 
false, we can always convert to the same datatype.

the "usual equality" is the coarsest equality we have - so the coarsest 
side of the hierarchy exists

it is so coarse, that it even isn't transitive (e.g. approximate 
equality for decimals)

After reading that wiki about identity, almost all of those criticisms 
of SAME? sound like CureCode tickets you haven't written yet. Carl's 
proposed bit-for-bit equality should solve most of those criticisms.

all, but I am not sure they are criticisms, they are just difference 
points

SAME? should mean "the same thing". Those difference points are bugs.

In R2, where as-binary is an alias:
>> a: "aa" same? a as-binary a
== false

Differing word types should behave the same, even when bound to the 
same context.
