Change your eval() to
eval "use $mod; 1;"
which forces a true value to be returned if 'use' runs successfully.

The second and third are the same. The first one, a

Hi Eri,
I would suggest dispensing with the comma operators. They can have some rather
unexpected effects in this context. Remember--variables within full quotes are
interpolated before the string is taken. So you could write the above as:

Having a quick look, I may say your ploblem can be solved with hash references.
Something like:
my %hash_level1=();
my %hash_level2=();
$hash_level1{'tag'}=\%hash_level2;
To retrieve a value form hash_level2:
my $hash_p= $hash_level1{'tag'};
Return ${$hash_p}{'tag_from_level2'};
Hope it helps,
