If the array actually represents a vector or matrix, then there's already a good library for it: PDL.

If not, chances are that there's already a good library for it on CPAN anyway ;-)

my $ret = &my_sub(@args);

In general there's no need to add the & in front of sub calls. On the contrary it has some effects that aren't desirable most of the time, like disabling prototype checking.
