0.8.8.9:
	Reinstate some compiler transforms for STRINGoid types.
	... since STRING is now a union type, some compiler transforms
		would give up (unnecessarily) with arguments of such
		a type, even when the conditions were otherwise
		favourable;
	... extend the logic in those transforms to deal with arrays
		with the same 'shape' but different specialized
		array element type
