Do we need to support /disjunction/ as well? E.g.,
:depends-on ((OR (FEATURE :SBCL :SB-THREAD) (FEATURE :ALLEGRO :SOME-ALLEGRO-THREADING-THING)))
or even implication? Let's assume, for example, that allegro has threading always, but SBCL not so:
I think arbitrary feature expressions composed of :OR, :AND, and :NOT -- "just like in the reader" are what I'm after. My initial example should have used ((FEATURE (:AND :SBCL :SB-THREAD))), I guess.
since this is really a pretty substantial change to the API, and programmers need to be able to detect whether the ASDF is able to handle it.
No big opinions on this. Cheers, -- Nikodemus
