I doubt it; remember that local variables don't have names once they've been 
passed, and in fact there might not even be any variables. The user may have 
done:

	myfunc(1, 2, 3)

or

	myfunc()

...instead.

If you really need to do this kind of thing, I suspect that your only option 
is to use the debug library, look at your caller's stack frame, and then use 
undocumented internal nastiness to examine the byte code directly.

I suspect that the real answer to your question is 'You don't want to do 
that.' What are you trying to do?
