If I understand `MacroExpands` macro, it only gets invoked if the macro is used
therefore it would need to be called somewhere for the check to trigger. Your
code snippet will still error out with `MacroDefined` and `MacroExpands` won't
ever be invoked.
Is there a way to use the post-processor inside of `MacroDefined` to expand the
definition?
