If we did everyone would still say "@ISA = qw(Exporter)" to be
backwards compatible, so I don't know what the benefits would be.
Also it would cause "subroutine redefined" warnings in this sort of
code:
use Exporter;
sub import {
...
Exporter::export_to_level(...);
}

Plus I remember being impressed with Ada because you could write an
infinite loop without a faked up condition. The idea being that in Ada
the typical infinite loop would be normally be terminated by detonation.
