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