10 | =head1 DESCRIPTION |
|
|
11 | |
|
|
12 | This module implements AnyEvent's strict mode. |
|
|
13 | |
|
|
14 | Loading it makes AnyEvent check all arguments to AnyEvent-methods, at the |
|
|
15 | expense of being slower (often the argument checking takes longer than the |
|
|
16 | actual function). |
|
|
17 | |
|
|
18 | Normally, you don't load this module yourself but instead use it |
|
|
19 | indirectly via the C<PERL_ANYEVENT_STRICT> environment variable (see |
|
|
20 | L<AnyEvent>). However, this module can be loaded at any time. |
