141 Returns a boolean as to whether or not warnings are enabled for the warning
142 category C<w>. If the category is by default enabled even if not within the
143 scope of S<C<use warnings>>, instead use the L</ckWARN_d> macro.

152 Like C<L</ckWARN>>, but takes two warnings categories as input, and returns
153 TRUE if either is enabled. If either category is by default enabled even if
154 not within the scope of S<C<use warnings>>, instead use the L</ckWARN2_d>
155 macro. The categories must be completely independent, one may not be
156 subclassed from the other.

167 if not within the scope of S<C<use warnings>>, instead use the L</ckWARN3_d>
168 macro. The categories must be completely independent, one may not be
169 subclassed from any other.

178 Like C<L</ckWARN3>>, but takes four warnings categories as input, and returns
179 TRUE if any is enabled. If any of the categories is by default enabled even
180 if not within the scope of S<C<use warnings>>, instead use the L</ckWARN4_d>
181 macro. The categories must be completely independent, one may not be
