how to take a hash reference from main::,

rfb has asked for the wisdom of the Perl Monks concerning the following question:

Currently I'm

$session = \$main::session;

but that means I have to access the hash with

$$session->{'supa'}

is there a way I can dereference it with so I dont have to use double dollar signs?

If `$main::session` alread holds a reference to a hash, then just assign that value (the reference) to the new variable (do not introduce another level of references): `%main::hash = (one => 1, two => 2, three => 3); $main::session = \%main::hash; my $session = $main::session; print $session->{two};` [download]	[reply] [d/l] [select]
