In favor of this.

In the other thread Walter's solution is to write a delegate that 
uses no GC but isn't marked @nogc. This is were such a attribute 
could intervene.

It would be a nice symmetry with @safe/@trusted/@system if we had 
@nogc/@trustedgc/@gc but then perhaps not the mental load most 
people want ouf ot stuff they don't care about. But if I don't 
care about @safe, @trusted helps me a lot more.
