METHODS

27       tie HASH, 'Hash::Case::Preserve', [VALUES,] OPTIONS
28           Define HASH to be case insensitive, but case preserving.  The hash
29           is initialized with the VALUES, specified as ref-array or ref-hash.
30
31           OPTIONS is a list of key/value pairs, which specify how the hash
32           must handle preservation.  Current options:
33
34           * keep => 'FIRST' ⎪ 'LAST'
35               Which casing is the prefered casing?  The FIRST appearance or
36               the LAST.  Only stores will affect the casing, deletes will
37               undo the definition.  Defaults to LAST, which is slightly
38               faster.
