Maybe I don't get this right but why you don't just use the
void[] as it is?
void[] mem = [i];

return (cast(T[]) mem)[0];
This is how I exchange variable data between DLLs.
That works, and is more elegant than the OP's solution.

Why do you think you need a `void[]` slice? I think `void*`
pointers are sufficient. This handles all normal data types, as
long as they are allocated on the GC heap:
I wanted to have the registry own the structs' memory, though
