I think this solution is a good idea but that removing or restricting
anything more regarding with is a bad idea as others have pointed out.

I'm using with quit a lot and it was one of thous things that attracted me
to D (I get the feeling that D has a quite pragmatic way of looking at
language features, if it's usefull lets have it unless it's harmfull to
other parts of D, sort of.).

On a similar note, Andrei, what is this spree of removing features? Ok some
are obviously bad, imaginary types for example, but why remove other stuff
such as commplex and with?
