Is there a way to check if a pointer is supposed to point to non-GC

I don't know of a simple way.

If not, maybe we could tag those non-GC-mangaged pointers with a UDA,
preferrably `@nogc`, and then build a trait, say, `hasGCIndirections`
that doesn't include @nogc-pointers.

What do you think?

Seems there'd be quite some annotational overhead. Some experience would be welcome.
