A side note - really just a personal preference of mine that might help you. Name variables what they are - if a scalar is a reference to a hash, name it as such. For example, if you pass a reference to a 'user' hash in to subroutine print_user, then do it this way:
sub print_user {
my $user_hashref = shift;
print "user name = $user_hashref->{'name'}\n";
print "user age = $user_hashref->{'age'}\n";
}
### main part of code ###
my %user = { "name" => "John Doe",
"age" => 12 }
print_user(\%user);
That way, you always know that scalar $user_hashref is really just a *reference* to the user hash, and it needs to be treated like a reference to a hash, instead of like an actual hash.
