This is cool, but even in unit tests for malloc wrapper there is only simple case with class without references to another class and no dtor.
If you examine the entire library, there are various use cases of nogc classes. For instance, a derived class containing references to other class objects [1]. I am not using classes heavily with D. I just once happily used dplug's nogc facilities. When I saw this thread, I just wanted to share it here.
Seems like the issue is that one have to add @nogc constructor/destructor overloads for emplace/destroy, and the author can't have @nogc dtor because of writeln (IIRC @nogc using GC is allowed with `debug` anyway), and all class members of another classes must recursively provide them as well.
I agree with you. D needs more nogc facilities for OOP. It would not be so hard to include those overloads. Probably, this would violate the strictly defended safety principles of D?
