This code:

auto v = new Vec(void);
Means having defined a struct with explicitly statically defined fields,
and then allocate one of it on the heap without initializing its fields.
It's equivalent to:
auto v = cast(Vec*)malloc(Vec.sizeof);
D is a language with C-like syntax and static typing. It pragmatically
combines efficiency, control, and modeling power, with ~~~>safety<~~ and
programmer productivity.
Unsafe stuff shouldn't be simple to type and why would you need language
support for a 1-liner?
ref T uninitializedAlloc(T)() @system pure nothrow
{
return *cast(T*)GC.malloc(T.sizeof);
}
The only argument I can see is the asymmetry to
Vec v = void;
