That doesn't seem to work. 

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dump;
use Symbol;

my $glob = Symbol::gensym;

warn "$glob\n";
dump $glob;

*$glob = { a => 1 };

warn "$glob\n";
dump $glob;

%{ *$glob } = ( 'a' => 1 );
@{ *$glob } = ( 1 .. 5 );

warn "$glob\n";
dump $glob;

Gives 

GLOB(0x225130)
do {
  require Symbol;
  Symbol::gensym();
}
GLOB(0x225130)
do {
  require Symbol;
  Symbol::gensym();
}
GLOB(0x225130)
do {
  require Symbol;
  my $a = Symbol::gensym();
  *{$a} = [1, 2, 3, 4, 5];
  *{$a} = { a => 1 };
  $a;
}

If I autovivify a hash (and an array) into the glob, dump shows them there, but although the reference assignment doesn't produce errors, dumping the glob after doesn't show anything in the hash slot?
