in thread Why does Perl have typeglobs?

Perl's symbol table is just a hash
Indeed. A hash of hashes, in a way: 
use warnings;
use strict;
sub T { 42 }
our $T = 24;
*T = *STDOUT{IO};
print { *T{IO} } ${*T{SCALAR}}, ' ', *T{CODE}->(), "\n";

    Not a hash of hashes, a hash of globs. Not only is the syntax different, so is the implementation. A glob is a struct, not a hash table.
