Parenscript ships with a helper macro like this:
(defpsmacro length (a) `(.size ,a))
But there's no "size" function for arrays or strings... in fact, is there a "size" function in JS?
.size() is a method from the Prototype library. That probably mixed up whoever put that in there.
For most things, it seems like one would want:
(defpsmacro length (a) `(@ ,a length))
I agree that is more general. I've pushed this fix out to the darcs repos.
