Looking at what you are trying to do here, I'm guessing you are trying to
"emulate" a complex data structure. You should just use one instead:
my %hash;
$hash{something}{withaperiod}="some text";
my $something='something';
my $withaperiod='withaperiod';
print qq{$hash{$something}{$withaperiod}\n};
That way you can use perl's built in constructs to iterate over the data
when you need to:
my $subhash = $hash{something};
foreach my $key ( keys %$subhash ) {
print("$key => $subhash->{$key}");
}
