Returns undef if the given utility was never in core or remains in core. .ie n .IP "removed_from_by_date( UTILITY )" 4 .el .IP "\f(CWremoved_from_by_date( UTILITY )\fR" 4 .IX Item "removed_from_by_date( UTILITY )" Takes a UTILITY name as an argument, returns the first perl version by release date where that utility was removed from core. Returns undef if the given utility was never in core or remains in core. .SH "DATA STRUCTURES" .IX Header "DATA STRUCTURES" These are the hash data structures that are available: .ie n .IP %Module::CoreList::Utils::utilities 4 .el .IP \f(CW%Module::CoreList::Utils::utilities\fR 4 .IX Item "%Module::CoreList::Utils::utilities" A hash of hashes that is keyed on perl version as indicated in $]. The second level hash is utility / defined pairs. .SH AUTHOR .IX Header "AUTHOR" Chris \f(CW\*(C`BinGOs\*(C'\fR Williams <chris@bingosnet.co.uk> .PP Currently maintained by the perl 5 porters <perl5\-porters@perl.org>. .PP This module is the result of archaeology undertaken during QA Hackathon in Lancaster, April 2013. .SH LICENSE .IX Header "LICENSE" Copyright (C) 2013 Chris Williams.
