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.

       Extends "DESCRIPTION" in Hash::Case.

METHODS
       Extends "METHODS" in Hash::Case.

   Constructors

       tie %hash, 'Hash::Case::Upper', [$values,] %options
           Define %hash to have only upper-cased keys.  The hash is
           initialized with the $values, specified as ARRAY or HASH.
           Currently, there are no %options defined.  Improves base, see
           "Constructors" in Hash::Case

   Hidden object access
       Extends "Hidden object access" in Hash::Case.
