Are stack-allocated (scoped) classes too gone?
De facto no, de jure yes.
I don't really understand this. Are they going to be gone or not?
In any case, can we at least keep them for unsafe D? Stack allocation is
not easy to do via placement new, the compiler is much better suited for
it, and stack allocating classes can be a huge performance gain. Until
we get full escape analysis, scope classes are the only option.
There's no need for a language feature. I am implementing stack
allocation for classes in library code; I'm just undecided on where to
put it.
