sub get_exon {
    return substr($_[0], $_[1] - 1, $_[2] - $_[1] + 1);

Note that by using $_[0] directly, you're accessing $chromosome without copying it. This is because the @_ array is aliased to the parameters passed. So this saves you a reference and a dereference on top of the savings that you would have when passing a reference, while you lose out on readability.
