An alias is always a variable true, that's an obvious no-brainer.
But typeglob mechanisms are only a part of the way to create them.
Especially in for my $a (@a) { ... } there is no symbol table entry like you claimed. my $a is a private variable and an alias.
And newer Perl versions allow activating the feature for refaliasing too, again no symbol table.
