I thought scrathpads worked differently.
I read several things in the docs that explicitly said they did, and it
has always confused me. Have they integrated? Or did I just DREAM it???
Lexicals aren't in the symbol table.
my $foo;
*can't* be accessed as $pack::foo, because it isn't IN a package.
Locals, on the otherhand, *have* to be package variables that can be
tracked by $pack::foo syntax. So how can
my @bar;
allow
local $bar[2];
to localize an element of @bar which isn't traceable through a package
name? It obviously works, but I don't see *how*.
~sigh~
