Nitpicking: `new` is typed (i.e. allocation+construction), `malloc` and `allocate` are not (only allocation). If you want allocation *and* construction with the new Allocator interface, you'll want to use the make[1] (and dispose[2] for the reverse path) template function; and they are a superset of `new`: You cannot, e.g., construct a delegate with new, but you can with `make`.
