User:Kevin Reid proposes that everything which is currently optEjector :nullOk[OneArgFunc] should instead be ejector :OneArgFunc, where the object throw is used instead of null to indicate not using an ejector. (The interfaces are compatible, in that both ejectors and throw support .run(:Exception).)

He considers the advantages to be regularity in many places: code to make use of an ejector is simpler, explanations need not mention null, and the type is simpler.

E-on-CL implements this proposal.
