warnings::pedantic - Dubious warnings for dubious constructs.

VERSION

Version 0.01

SYNOPSIS

This module provides a 'pedantic' warning category, which, when enabled, warns of certain extra dubious constructs.

use warnings::pedantic;

grep { ... } 1..10; # grep in void context
close($fh);         # close() in void context
print 1;            # print() in void context

Warnings can be turned off with

no warnings 'pedantic';

as well as

no warnings;

or

no warnings::pedantic;

Additionally, you can turn off specific warnings with

no warnings 'void_grep';
no warnings 'void_close';
no warnings 'void_print'; # printf, print, and say

ACKNOWLEDGEMENTS

The warning for void-context grep was at one point part of the Perl core, but was deemed too controversial and was removed. Ævar Arnfjörð Bjarmason recently attempted to get it back to the core as part of an RFC to extend warnings.pm, which in turn inspired this module.
