[parenscript-devel] "let over lambda" seems buggy

[Canhua]

actually what I want to achieve is something like this:
(create "fn_1" (let ((x))
			 #'(lambda ()
			     x))
           "fn_2" (let ((x))
	        	 #'(lambda ()
			     x)))
and I expected these two "x" are lexical-scope separate and so
independent from each other.
However the compiled js code doesn't work as I expected.
