DeferredGenerator<T> class final

The generator deferred returns, before and after it is defined.

Defined exactly once, and drawn from only after that. Both mistakes throw where they are made rather than producing a strange run: a generator with no definition has nothing to draw, and one defined twice means two recipes are in play and no reader can tell which the failure came from.
