I forgot to mention that you can use a continuation closure, something like this (untested):

my $test = sub { my $hr=shift; return $hr->{$var1}{$var2} };
foreach my $domain (sort {$a cmp $b} keys %{$hash}) {
   my $value = &{$test}($$hash{$domain});
}

Update: correction, as noted by chromatic. (I didn't make the other change, as it's merely ugly rather than wrong, and chromatic shows the nicer looking version anyway.)
