C-like syntax: foo(1, 2, 3); if (x) { aaa(); } else { bbb(); } Lisp-like syntax: (foo 1 2 3) (if x (aaa) (bbb)) Syntax is easy. Practical semantics is a little bit harder, but it's not hard. Editor-wise, you want an editor that does automatic indenting and some kind of matching parentheses highlighting. Emacs is one. (Once you've learned the language, you can use a fancy structural editor, but maybe don't confuse yourself with too many new things at once.)
