111	Non-composing generators with several input types	ghost	somebody	Generators which are not composing, but require two input files apepars to be subtly broken. First, if such generator is *passed* two source target the 'convert-to-consumable-types' method will call generators.construct again, for non-obvious reason. Second, if that returns a type that's derived from one of desired source type, we don't detect that, and bypass that target. Finally, we don't check that all required types are present.	defect	new	major		component1
