I want to learn new languages. But new as in "new to me", not new as in "created last week". So I decided to play with the grandaddy of all cool languages, LISP. Created in 1958, it's even older than I, which is good because it's experienced.
One "problem" with LISP is that there are a million LISPs. You can use Scheme or Common Lisp, or Emacs' Lisp, or a bazillion others. I wanted something simple so it was supposed to be Scheme... but a few days ago I ran into something called Picolisp and it sounded so cool.
