Yeah, but then you have to rewrite the sub and call SUPER:: or NEXT::
explicitly. It breaks encapsulation in a big way. Really, it should be
avoided at all costs. There's lots of -objects RFC's that fix stuff like
this, but your proposal of a single AUTOGLOB would break them.
We've already got 50+ special subs, 3 extra ones for AUTO* buys you a
lot and doesn't cause namespace pollution worth worrying about. Plus
what's the probability that someone is going to want to name their sub
"AUTOHASH" anyways?
Matching with
if($type_of_thing eq 'SCALAR') # would be ref type
is kludgey at best. And the likelihood that other fundamental types will
be added to Perl is pretty low. Plus, I would think we'd want to control
what was auto-globbable.
