NAME
       Hash::Case::Preserve - hash with enforced lower cased keys

INHERITANCE
	Hash::Case::Preserve
	  is a Hash::Case
	  is a Tie::StdHash

SYNOPSIS
	use Hash::Case::Preserve;
	tie my(%cphash), 'Hash::Case::Preserve';
	$cphash{StraNGeKeY} = 3;
	print keys %cphash;	    # StraNGeKeY
	print $cphash{strangekey};  # 3
	print $cphash{STRANGEKEY};  # 3

DESCRIPTION
       Hash::Case::Preserve extends Hash::Case, which lets you play various
       trics with hash keys.  See Hash::Case for the other implementations.

METHODS
       $obj->addHashData(HASH)

	   See "METHODS" in Hash::Case

       $obj->addPairs(PAIRS)

	   See "METHODS" in Hash::Case

       $obj->setHash(HASH)

	   See "METHODS" in Hash::Case

       tie(HASH, 'Hash::Case::Preserve', [VALUES,] OPTIONS)

	   Define HASH to be case insensitive, but case preserving.  The hash
	   is initialized with the VALUES, specified as ref-array or ref-hash.

	   OPTIONS is a list of key/value pairs, which specify how the hash
	   must handle preservation.  Current options:

	    Option--Default
	    keep    <required>

	   . keep => => 'FIRST' | 'LAST'

	       Which casing is the prefered casing?  The FIRST appearance or
	       the LAST.  Only stores will affect the casing, deletes will
	       undo the definition.  Defaults to LAST, which is slightly
	       faster.
