Hash::Case::Lower - hash with enforced lower cased keys

       Hash::Case::Lower 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 lower-case.

       Extends "DESCRIPTION" in Hash::Case.

        Hash::Case::Lower
          is a Hash::Case
          is a Tie::StdHash

           Define  HASH  to  have  only lower cased keys.  The hash is initialized with the VALUES, specified as
           ref-array (with key value pairs) or ref-hash.  Currently, there are no OPTIONS defined.
