I've used @nogc as simple diagnostic, shows where it can allocate
inside hot paths, other than that - never.
But now there is also -vgc flag for this task which is less
intrusive but also less "precise".
One can allocate classes without GC and handle its lifetime
manually, there is actually whole class of tasks where one might
need it (high-frequency trading, realtime software such as
machinery controllers, game engines and games to some extent...).
There is also extern(C++) classes that can be used when you are
limited to BetterC (for example WASM) or other low level software
or even highly specific low level C++ interoperability where
regular extern(C++) class just doesn't works (diamond problem,
