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
Sunanda

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.
BrianH

[15652]
Aside from that bug, I've seen no changes. AS-PAIR might go native 
though.

so when will the plugin interface be documented?
BrianH

[15654]
It's not even done yet. After this month I guess.

is binary a string?
Carl wants opinions to help him decide:

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

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 :-)
Sunanda
22-Jun-2009
[15659]
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 :)
Ladislav
22-Jun-2009
[15661x2]
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
BrianH
22-Jun-2009
[15663]
So SAME? is less strict than STRICT-EQUAL? for words?
Ladislav
22-Jun-2009
[15664x2]
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
BrianH
22-Jun-2009
[15666x2]
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?
Ladislav
22-Jun-2009
[15668x3]
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).
BrianH
22-Jun-2009
[15671]
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.
Ladislav
22-Jun-2009
[15672x2]
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)
BrianH
22-Jun-2009
[15674]
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.
Ladislav
22-Jun-2009
[15675]
all, but I am not sure they are criticisms, they are just difference 
points
BrianH
22-Jun-2009
[15676x2]
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.
Ladislav
22-Jun-2009
[15678x2]
if we want the hierarchy to be linearly ordered by fineness, then 
the equality should compare just spelling of words, the second one 
- finer and non-existent yet, should compare spelling and binding, 
the third one should compare spelling + binding + datatype (can be 
strict-equal?), the fourth one is not that necessary in this case
my IDENTICAL? may be considered a "quirk", taking into account even 
such thing as the New-line bit

BrianH: if binary and string types are more divorced, what do we 
gain in particular?
BrianH
22-Jun-2009
[15681x2]
We gain a host of potential new abilities to work with binaries. 
Right now the half-assed way that binaries sometimes act like strings 
is making it difficult to process binaries like binaries. Getting 
rid of the false equivalency will make all sorts off improvements 
possible.
Including proper, powerful support for binaries in PARSE.

better bit twitteling would be good

[15684x2]
Ladislav, just checked your SAME? criticisms from the wiki against 
R3, and only the date! transitivity thing still applies.
Struct! is not implemented, nor is denomination in money!. Closed 
ports are not errors and decimals are fixed. Unset and error are 
still not values. The only thing left is the date! zones and the 
type-ignorant any-word comparisons.
Ladislav

how about my last comment to r3blog?

I hadn't noticed the new blog post. Replied there.

SAME? meaning same bits should include the type flags too - otherwise 
same bits is meaningless or cooincidental.

Maxim, now you can defend your copy deep on object issue - http://www.rebol.net/r3blogs/0212.html
BrainH: btw - Meijeru's identity confirmed - http://users.telenet.be/rwmeijer/
, he now mentions REBOL - http://users.telenet.be/rwmeijer/proglang/

Cool - we need as much help as we can get. I'm glad he participates 
in the chat too, and his testing has been very helpful.
One more mystery person to go: Peta, are you out there? :)

The bug fixes just keep coming -- Alpha 59 out barely a day after 
A58:

Curecode #961 was fixed in less than 24 hours....That must be a record!

Notice Meijeru's daytime work... must be a fruitful hobby.
