NAME
       perllexwarn - Perl Lexical Warnings

DESCRIPTION
       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.
