=head1 Warning and Dieing

Returns a boolean as to whether or not warnings are enabled for the warning
category C<w>. If the category is by default enabled even if not within the
scope of S<C<use warnings>>, instead use the L</ckWARN_d> macro.
=for apidoc Am|bool|ckWARN_d|U32 w
Like C<L</ckWARN>>, but for use if and only if the warning category is by
default enabled even if not within the scope of S<C<use warnings>>.
=for apidoc Am|bool|ckWARN2|U32 w1|U32 w2
Like C<L</ckWARN>>, but takes two warnings categories as input, and returns
TRUE if either is enabled. If either category is by default enabled even if
not within the scope of S<C<use warnings>>, instead use the L</ckWARN2_d>
macro. The categories must be completely independent, one may not be
subclassed from the other.

Like C<L</ckWARN2>>, but for use if and only if either warning category is by
default enabled even if not within the scope of S<C<use warnings>>.
=for apidoc Am|bool|ckWARN3|U32 w1|U32 w2|U32 w3
Like C<L</ckWARN2>>, but takes three warnings categories as input, and returns
TRUE if any is enabled. If any of the categories is by default enabled even
if not within the scope of S<C<use warnings>>, instead use the L</ckWARN3_d>
macro. The categories must be completely independent, one may not be
subclassed from any other.

is by default enabled even if not within the scope of S<C<use warnings>>.

TRUE if any is enabled. If any of the categories is by default enabled even
if not within the scope of S<C<use warnings>>, instead use the L</ckWARN4_d>
macro. The categories must be completely independent, one may not be
subclassed from any other.
