remove accepts none. the others are examples for "give a good value 
for 'if instead of throwing an error".

Well, if you consider index? find to be another way of saying find/index 
(if such a thing existed) then I can see why you would let it accept 
none. If you consider index? to be a seperate function, then accepting 
none would just be propagating an erroneous condition. Remove should 
definitely accept none because it's not much of a stretch to change 
its meaning from "remove here" to "remove here if there is something 
to remove, no-op if inapplicable", the same behavior it has as in 
 remove tail series.

But Remove Tail Series is programatically different than Remove None 
as Tail returns an apparently empty series, not none.

Except in a more abstract sense that  remove tail x  and  remove 
none  both return what they were passed, unmodified :)

is this a bug or am I doing something wrong?

t: func [ip-val [word!]] [
    switch/default ip-val
    [
        'From [print "A"]
        'To [print "B"]
    ]
    [print "C1"]
]

t 'From ; should print "A"

Compared to 

t1: func [ip-val [string!]] [
    switch/default ip-val
    [
        "From" [print "A1"]
        "To" [print "B1"]
    ]
    [print "C1"]
]

t1 "From" ; should print "A1"

which correctly prints "A1"

The first example prints "C1" rather than "A"

t 'From => ?

>> t: func [ip-val [word!]] [
[        switch/default ip-val
[        [
[                'From [print "A"]
[                'To [print "B"]
[            ]
[        [print "C1"]
[    ]
>>
>> t 'From ; should print "A"
C1
>>

shouldnt that have printed A rather than C1

>> t: func [ip-val [word!]] [
[        switch/default ip-val
[        [
[                From [print "A"]
[                To [print "B"]
[            ]
[        [print "C1"]
[    ]
>> t 'from
A

OK ... so I dont need the "'" before the word ..... thanks

I remember being caught on that one once before.

I note that the parts of  dates, times, tuples etc are accessible 
using path notation.
Why not email! as well?

I would suggest that email/1 should be the part before the "@", and 
email/2 the bit after.
Then email/2/1 would access the first bit before the "." etc.

Graham: Are you asking for  email/1 & email/2 to map to the current 
email/user and email/host  refinements ?

oh no!

where was this documented??

under datatypes  http://www.rebol.com/docs/core23/rebolcore-16.html#section-2.3

:)

No doc ? We even don't read the one we have ;-)

Q: is there something to flatten a block of block ?
ie: 
>>> probe a
=== [[1 toto] [2 "this is text" 5.63] [#as12 none]]
>>> magic-code! a
=== [1 toto 2 "this is text" 5.63 #as12 none]

Yes this just came up again recently,

27 april  chat & parse

Thanks, didn't remember that

how is find/match supposed to work on blocks? I thought following 
will work? 

find/match ["Petr Krenzelok"] "Petr"

what I have in mind is very simple kind of select, not needing to 
enter whole search key ...

with blocks, I don't think that'll work with match, because it searches 
for the full element in a series, thus you need to search in two 
levels...

the block level and the string level

a find/deep would be very useful... recursive searching of blocks 
and objects. it could allow you to find a value in large objects 
and blocks quickly

find/deep is long requested feature, but it was said as not being 
as trivial, as blocks can contain self-references etc ...

and what is find/only about?

with find/match you can check for abbreviations

>> find/match "Hello World" "W"    
== none
>> find/match "Hello World" "H"
== "ello World"

>> find/match ["Pekr" "Krenzelok"] "Pekr"
== ["Krenzelok"]
>> find/match ["Pekr" "Krenzelok"] "Krenzelok"
== none

/only is for this:

>> find ["Pekr" "Krenzelok" "asking"] ["Pekr" "Krenzelok"]
== ["Pekr" "Krenzelok" "asking"]
>> find/only ["Pekr" "Krenzelok" "asking"] ["Pekr" "Krenzelok"]

>> find/only [["Pekr" "Krenzelok"] "asking"] ["Pekr" "Krenzelok"]
== [["Pekr" "Krenzelok"] "asking"]

I wrote some functions of this kind, but anyway, what is "the shortest" 
reverse of:

    y: to integer! x: #{80000000}

Maybe this ?
>> reverse third make struct! [i [int]] reduce [y]
== #{80000000}

; quick testing looks good

>> foreach v [-1 0 1 1000 7777 2000000][print same? v to-integer 
reverse third make struct! [i [int]] reduce [v]]
true
true
true
true
true
true

hmm, a "short" way could be:

>> to binary! reduce [y / 16777216 y / 65536 y / 256 y]
== #{80000000}

btw, is this on rambo? i really think that to binary! should work 
with integers.

I second that.

I don't remember seeing that in rambo.

Doesn't appear to be there. I searched "binary!" and "binary"

does anybody know why code below give me diffrent results? looks 
like get/set funcs operate on diffrent contexts:

ctx: context  [
  no-a: no-b: no-c: none
  set 'test does [
    foreach x [no-a no-b no-c] [set x "test-1"]
    foreach x [a b c] [set (to-word join "no-" x) "test-2"]

    foreach x [a b c] [print [join "no-" x get (to-word join "no-" x)]]
    foreach x [no-a no-b no-c] [print [x get x]]
  ]
]

test
probe no-a
probe ctx/no-a

to-word creates global words
