Additional proposal:

In non-release mode, at the start of @nogc function, a thread-local  
variable __nogc is incremented. At the end, __nogc is decremented. Then if  
any GC calls occur when __nogc is nonzero, an error is thrown.

This would be for debugging only, and I'm thinking specifically to prove  
absolutely no hidden compiler-generated GC calls, or calls via extern(C)  
functions occur.
