Yes, but now you explicitly pass an array reference. As you have said,
this is better for readability. If this is just any darn subroutine that
you are using yourself, you shoud do it this way (Actually, then I
wouldn't prototype at all). But, if this is being exported, what is the
harm of "sub testsub ([EMAIL PROTECTED])"? If a beginner can understand the concept
of prototyping and referencing, I think they can gather an array
reference is being passed. When you program for an end-user programmer,
you should use [EMAIL PROTECTED] if you prototype something like this.
