I meant that a macro with arguments should become a macro with arguments.
This obviously buries the idea of having two AU_ALIAS'es.

On the other hand, a macro with exactly 0 arguments should become a macro
with 0 arguments. Macros with 0 arguments don't have parentheses, so it
shouldn't be a problem.

I'll have a look whether it's possible to implement AU_ALIAS in such way.
