If user don't have the access to the wrapped internal type there should 
be no problem. E.g. the wrapped type is private and only usable inside 
the PRNG's module. Then having public alias for RefCounted!PRNG touted 
as THE PRNG should suffice. (Truly wicked folks can crack open it with a 
carefully applied piece of template deduction but each to their own goals).


If you are afraid of these dark mages of templates you can do something 
like:

struct RefPRNG{
	RefCounted!PRNG payload;
	mixin ForwardCallsTo!"payload";
}

And let them suck it down. IMHO there is no reason to go that far.

See above I don't see the problem.
