+=for apidoc Am|bool|ckWARN|U32 w
+
+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|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
