that was my template does, actually. ;-)
public T zeroed(T) () if (__traits(isPOD, T)) {
import core.stdc.string : memset;
T res = void;
memset(&res, 0, res.sizeof);
return res;
}
due to compiler optimisation of struct returns this is almost the same as
inlining call to `memset()`.

i wonder why it works.

yet dmd still insists on having that `.init`. and there are no non-zero
defaults for winapi bindings, so i'm fine with such hacks. ;-) my own
modules are built properly by my build system, so there are `.init`s for
all necessary structs.
