This is the sort of thing that prototypes are good for. You get to pass variables seemingly by value, but it is really a reference that is passed. That allows the original variable to be modified. 

sub mogrify (\$\$\$) {
    my ($xref, $yref, $zref) = @_;
    # do stuff to $$xref and friends
    1;
}

mogrify $x, $y, $z;

That will mogrify the variables in place.
