I am not entirely sure but I think in all cases you can just get a new reference via your typeglob-syntax.

Consider this:

use strict; use Scalar::Util qw(weaken isweak); my $a = 1; my $r1 = *main::a{SCALAR}; my $r2 = *main::a{SCALAR}; weaken $r1; print "r1 is weak\n" if isweak $r1; print "r2 is weak\n" if isweak $r2;

Here I get two copies of the typeglob. Both are references to $a but they are different one as proved by weakening one and observing that the other one has not been weakened.

So I guess you don't need the special snytax for array-refs, hash-refs etc, you just generically get a new copy of whatever is in the corresponding slot of the typeglob.
