RE: Actually a feature that I've always wanted is to be able to pass arrays byref or byval

I can't think of many reasons to pass an array byval. The only one I can think of is if you wanted to edit or redim the data of the original array without changing its data. Surely in either case a memcpy to a newly dimmed array would suffice. So really it's memcpy not passing arrays byval you really want.
