It appears as though there might be a gap in the lexical scoping implementation in the compiler:
(ps (lambda (x) (let ((x 1)) (foo x)) (incf x))) => "function (x) { var x = 1; foo(x); return ++x; };"
vs.
(ps (let ((x 10)) (let ((x 1)) (foo x)) (incf x)))
"var x = 10; var x33 = 1; foo(x33); ++x;"
Although function parameters have their own lexical bindings, the environment still needs to be informed of those bindings so that LET forms in the function body can rename any conflicts.
