tiny perceus fix, but mostly wrote match+rb-tree f-expr/macro for newLisp and benchmarked it. kraken 5-15x faster than newlisp-rbtree-macro, 137x faster than newlisp-rbtree-fexpr. I was suprised at first that the macro and fexpr versions were so close at 8.7x (while interpreted kraken rbtree is 50,000x slower), but after thinking about it it makes sense - the Kraken version has slowdown exponential in the multiple levels of f-exprs ('match' is an fexpr, but then so is 'let' and 'and' and 'lambda'), whereas the newLisp f-expr runtime expands to fast builtins ('let', 'and', etc). And all that exponential f-expr slowdown gets compiled away in Kraken!
