> I tried a "wrapper" type using opDispatch in dcollections, but what
I ran into is, opDispatch uses its called parameter types to decide
the function parameter types, you have very little control over that.
I basically ended up abandoning the use of opDispatch and implemented
each covered function by hand.

I managed to get this far (my file attached), using D-style runtime
variadic functions... it seems to work well in most cases, with the
notable exceptions being:
(1) Things I already mentioned
(2) Possibly ref/out/lazy parameters (I haven't tested them yet)

Any thoughts?
