       perllexwarn - Perl Lexical Warnings

       Perl v5.6.0 introduced lexical control over the handling of warnings by
       category.  The "warnings" pragma generally replaces the command line
       flag -w.  Documentation on the use of lexical warnings, once partly
       found in this document, is now found in the warnings documentation.
