How about some __initialize magic?

[russhy]

I would love to be able to do:


```D

T* t = alloc();

(*t) = .{};

// or better
t.* = .{};

// then we could also go ahead and be able to do like:
t.* = .{ field_a: 1, fiels_2: 2 }

```


Basically relaxing that rule:

Other languages do that, and i love them

Don't let us stay behind because we refuse to more forward!
