I must admit I'm confused by the intent of theleftsock (who seems to have chosen a very complicated way to do a fairly simple thing), but I'm also confused by the intent of the extra lexical scalar  $returned_hash_ref present in your reply. What does this give you (other than another maintenance worry) that you do not get from the hash and key you already have in hand? 

>perl -wMstrict -le
"sub S { print 'hi ', $_[0] }
 sub T { print 'lo ', $_[0] }
 sub U { print '-- ', $_[0] }
 my %hash = (
   my $x = L => \&S,
   my $y = M => \&T,
   my $z = N => \&U,
   );
 print $x;
 $hash{$x}->($x);
 $hash{L} ->('L');
 $hash{$_}->($_) for qw(L M N);
"
L
hi L
hi L
hi L
lo M
-- N
