If perl knew the array was going to be thrown away at the end of the statement, and that all indexed look ups were within the bounds of the original.

Its a big if, hence the reason I mentioned Python's tuples, which could be seen from a perl perspective to be a form of compiler hinting, telling the compiler that an AV need not be constructed. You could prototype the syntax using a RO AV for instance.
