-=head1 NAME
-
-warnings - Perl pragma to control optional warnings
-
-=head1 SYNOPSIS
-
- use warnings;
- no warnings;
-
- use warnings "all";
- no warnings "all";
-
- use warnings::register;
- if (warnings::enabled()) {
- warnings::warn("some warning");
- }
-
- if (warnings::enabled("void")) {
- warnings::warn("void", "some warning");
- }
-
- if (warnings::enabled($object)) {
- warnings::warn($object, "some warning");
- }
-
- warnif("some warning");
- warnif("void", "some warning");
- warnif($object, "some warning");
-
-=head1 DESCRIPTION
-
-If no import list is supplied, all possible warnings are either enabled
-or disabled.
-
-A number of functions are provided to assist module authors.
-
-=over 4
-
-=item use warnings::register
-
-Creates a new warnings category with the same name as the package where
-the call to the pragma is used.
-
-=item warnings::enabled()
-
-Use the warnings category with the same name as the current package.
-
-Return TRUE if that warnings category is enabled in the calling module.
-Otherwise returns FALSE.
-
-=item warnings::enabled($category)
-
-Return TRUE if the warnings category, C<$category>, is enabled in the
-calling module.
-Otherwise returns FALSE.
-
-=item warnings::enabled($object)
-
-Use the name of the class for the object reference, C<$object>, as the
-warnings category.
-
-Return TRUE if that warnings category is enabled in the first scope
-where the object is used.
-Otherwise returns FALSE.
-
-=item warnings::warn($message)
-
-Print C<$message> to STDERR.
-
-Use the warnings category with the same name as the current package.
-
-If that warnings category has been set to "FATAL" in the calling module
-then die. Otherwise return.
-
-=item warnings::warn($category, $message)
-
-Print C<$message> to STDERR.
-
-If the warnings category, C<$category>, has been set to "FATAL" in the
-calling module then die. Otherwise return.
-
-=item warnings::warn($object, $message)
-
-Print C<$message> to STDERR.
-
-Use the name of the class for the object reference, C<$object>, as the
-warnings category.
-
-If that warnings category has been set to "FATAL" in the scope where C<$object>
-is first used then die. Otherwise return.
-
-
-=item warnings::warnif($message)
-
-Equivalent to:
-
- if (warnings::enabled())
- { warnings::warn($message) }
-
-=item warnings::warnif($category, $message)
-
-Equivalent to:
-
- if (warnings::enabled($category))
- { warnings::warn($category, $message) }
-
-=item warnings::warnif($object, $message)
-
-Equivalent to:
-
- if (warnings::enabled($object))
- { warnings::warn($object, $message) }
