So, say `reg` is your allocator, your workflow would be
auto obj = reg.make!Type(args);
/* do stuff */
reg.dispose(obj); // If Type has a __dtor, it will call
obj.__dtor

If I do sucessive calls to reg.make!X where X are different
kinds of classes of different sizes how does reg.dispose(obj)
figure out at which address(es) (where emplace filled in the
data) the objects reside?
It can't figure out. With custom allocators you have to
manually do
the memory management, so the responsibility of when and which
object needs
to be destroyed falls on the user of the custom allocator.
IMHO, such a complexity should be wrapped in a typed allocation
layer. Have Andrei spoken anything about `TypedAllocator`(s) to
wrap this complexity?
