I can rewrite Binderoo with type functions, which essentially 
take one type (user or function types) and transform it in to 
something else.

But higher level. It will fundamentally change the way you 
approach metaprogramming. Even now, we have that thing that 
Andrei will say about C++. Where D is multiple languages under 
one banner. Writing D code can be as complicated as C#, but get 
in to DbI and it's a different language you need to learn. So I 
put it this way.

"Can you write a function?"
"Then you can do hardcore metaprogramming."

It's going to be a paradigm shift to get it in to a language like
