fixed a bug in expanding macros in definition context where the scope would get messed up when the macro call appears inside let/letrec-syntax. Basically, in the following example, (let-syntax ([id-macro (syntax-rules () [(_ x) x])]) (let () (define (foo) (display "not ok\n")) (let-syntax ([foo (syntax-rules () [(_) (display "ok\n")])]) (id-macro (foo))))) the call to (id-macro) would make (foo) refer to the foo in the internal-definition context (the not ok one) instead of the let-syntax one. On the plus side, macro expansion is now half a second faster!
