I'm afraid, when you add a new method to a Function class (by prtotyping), you are actually adding it to all declared functions, AS WELL AS to your copyArray(). In result your copyArray() function gets recursivelly self-referenced. I.e. there should exist copyArray().bind() method, which is calling itself.

In this case some browsers might prevent you from creating such reference loops and fire "function not defined" error.

Inline code would be better solution in such case.
