SKILL++ is actually a pretty compliant Scheme, with a lot of compatibility to SKILL and quite a bit of Common Lisp added on top. What makes it a bit funny is the clever parser, which allows both prefix syntax as in (setq x (plus a b)) as well as x = a + b (which just reads as the former expression). Personally, I prefer the Lisp style much - except for math expressions.
