Hash::Case::Upper - native hash with enforced lower cased keys

 Hash::Case::Upper
   is a Hash::Case
   is a Tie::StdHash

 use Hash::Case::Upper;
 tie my(%uchash), 'Hash::Case::Upper';
 $uchash{StraNGeKeY} = 3;
 print keys %uchash;  # STRANGEKEY

Hash::Case::Upper extends Hash::Case, which lets you play various trics with hash keys. In this implementation, the fake hash is case insensitive and the keys stored in upper-case.
