+=head2 investigate removing int_macro_int from POSIX.xs
+
+As a hang over from the original C<constant> implementation, F<POSIX.xs>
+contains a function C<int_macro_int> which in conjunction with C<AUTOLOAD> is
+used to wrap the C functions C<WEXITSTATUS>, C<WIFEXITED>, C<WIFSIGNALED>,
+C<WIFSTOPPED>, C<WSTOPSIG> and C<WTERMSIG>. It's probably worth replacing
+this complexity with 5 simple direct wrappings of those 5 functions.
+
+However, it would be interesting if someone could measure the memory usage
+before and after, both for the case of C<use POSIX();> and the case of
+actually calling the Perl space functions.
