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'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
