> Interesting idea. Unless I'm misunderstanding something, it seems to me you could kill both birds with one stone. If we add an 'importable' predicate to the '#if' language, then you can already use that to conditionalize the import:
> #if importable(ThirdPartyLibrary)
> import ThirdPartyLibrary
> /* decls that depend on library */
I am totally on board with that idea… since you could declare a type outside of the “#if importable” scope and add an extension inside the scope.
