Yes, I know. Hence my thought that I have to do this with macros. It's a
shame that the function option including lambda's don't have this
metadata as well.

Indeed. I am using this myself, and putting arglists in like
'([individual & classes][ontolology individual & classes])
which only works because I can distinguish between all the entities by
type (they are java objects), so disambiguiate.
Well, I guess I will code up a simple macro; in my current case, I can
infer the arglists anyway.
Thanks for the help!
