We already have the generics can the preprocessor symbols. That leaves the 
"for in". The development team has its doubts about the "for in" 
construct, but:

* Andreas did it in a reasonably clean way with a lot less hacks and 
  ugly constructions than Delphi did.
* The pressure on us is increasing to have a "for in".

I'm not totally happy with the hardcoded method names Andreas used, but 
his implementation could be used as a base to build on.

I think a Wiki article per improved suggestion is better, so every one can 
comment on it.
