One thing we need to add is a constant type to initialize pads. It's
perfectly acceptable, and in fact a design goal, to have a PMC in
multiple pads with the same name.
So, for example, if you had:
my $foo;
{
my $bar;
$foo = 12;
}
at the perl level, there'd be two pads, one for the block and one for
the outer scope. The PMC for $foo would be in *both* of them, and the
lookup wouldn't go past the inner pad. (And the lookup would be by
number rather than name as well, since we know the position in the
pad of the lexical)
>Also, should open_lex/close_lex be named new_pad/close_pad instead?
Yeah, I think so. Or new_pad/pop_pad, since we may keep the pad
around when we take it off the current pad stack.
