NAME

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

INHERITANCE

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

SYNOPSIS

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

DESCRIPTION

       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.

METHODS

       $obj->addHashData(HASH)
           See "Constructors" in Hash::Case

       $obj->addPairs(PAIRS)
           See "Constructors" in Hash::Case

       $obj->setHash(HASH)
           See "Constructors" in Hash::Case

       tie(HASH, 'Hash::Case::Upper', [VALUES,] OPTIONS)
           Define HASH to have only upper cased keys.  The hash is initialized with the VALUES,
           specified as ref-array or ref-hash.  Currently, there are no OPTIONS defined.
