That's surprisingly complicated for what I thought was a simple task: 
sub schlep
{
        my ($p,$q,%p2q) = @_;

        @{$q}{values %p2q} = @{$p}{keys %p2q};
}

Of course, this does assume that values and keys will always output in precisely the same order. Not that I have been given any reason to believe that they would do something to the contrary.
