Binary package “libtie-hash-regex-perl” in ubuntu trusty

module to match hash keys using regular expressions

 The Tie::Hash::Regex module allows hash keys to be matched using regular
 expressions.
 .
 In comparison to Tie::RegexpHash, rather than using regexps as keys that match
 against fetches, Tie::Hash::Regex allows the use of standard keys that are
 matched by regexps in fetches.
