3AnyEvent::Strict - force strict mode on for the whole process
4
5=head1 SYNOPSIS
6
7 use AnyEvent::Strict;
8 # strict mode now switched on
9
10=head1 DESCRIPTION
11
12This module implements AnyEvent's strict mode.
13
14Loading it makes AnyEvent check all arguments to AnyEvent-methods, at the
15expense of being slower (often the argument checking takes longer than the
16actual function).
17
18Normally, you don't load this module yourself but instead use it
19indirectly via the C<PERL_ANYEVENT_STRICT> environment variable (see
20L<AnyEvent>). However, this module can be loaded at any time.
