=head1 NAME
tainting - Enable taint mode lexically
=head1 VERSION
This document describes version 0.02 of tainting (from Perl distribution tainting), released on 2017-07-04.
=head1 SYNOPSIS
To enable tainting in a lexical block:
{
use tainting;
# tainting is enabled
}
# tainting is disabled again
To disable tainting in a lexical block:
use tainting;
{
no tainting;
# tainting is disabled
}
# tainting is enabled again
=head1 DESCRIPTION
This module provides a simpler interface to L<Taint::Runtime>. The idea is so
that there is no functions or variables to import. Just C<use> or C<no>, like
L<warnings> or L<strict>. Tainting of C<%ENV> will be done one time
automatically the first time this module is used.
Please (PLEASE) read Taint::Runtime's documentation first about the pro's and
con's of enabling/disabling tainting at runtime. TL;DR: Use -T if you can.
