Does there need something to be suggested per se? 

What do you think of the DECAL solution ? It's ackward, but that is because
it is pre-generics, and I think generics would solve many of the problems.

I don't like for-in, but if sb wants to waste time on it, better do it
Delphi compat. I don't see the need for anything else, and if people see it,
it would be nice to hear what they think of the decal principle (but then
fixed with generics)

The Prism solution might be overly costly since it depends on a continuation
concept.
