Feature #6242
closedRuby should support lists
Description
I've heard that Ruby is a LISP.
LISP stands for "LISt Processing."
Hence, Ruby should support lists.
I've attached a patch to add the classes List and Cons, and the cons operator `:::'.
Example:
S[1,2,3].inject(:+)
=> 6
S[1,2,3]
=> S[1, 2, 3]
0 ::: S[1,2,3]
=> S[0, 1, 2, 3]
0 ::: 1 ::: 2 ::: 3 ::: nil
=> S[0, 1, 2, 3]
S[1,2,3].inject(:+)
=> 6

Updated the patch to evaluate x ::: y' as
y.:::(x)', not `x.:::(y)'.

Updated the patch to add methods: foldl, foldr, +, flatten/concat, map, flat_map/concat_map,
filter, length/size, sum, reverse.

Thanks for the information. I forgot to propose macros.
But the following comment reminded me that Ruby was originally Smalltalk, not a LISP.

I'm afraid this issue might be rejected.

Hi,shugo
What benefits of the proposed lisp changed? I am very confuse this LISP list feature. your sample is very similar with native ruby Hash in my options.

Maybe we should propose a free ":" after method names for keyword arguments in a separate issue, like:
open: "file.txt", mode: "r+", encoding: Encoding::UTF_8 do |io|
# …
end
Then we can have the best of LISP and Smalltalk

I used to think so too, until I saw this:

Clearly Ruby has been a stealth-Lisp all along.

Ah! Our old friend Pascal… I remember him well. I ran across him not to long ago. Seems he's moved on to Lua now: http://article.gmane.org/gmane.comp.lang.lua.general/81364/match=
