Is void initialization not good enough?
IIRC it's something like:
ubyte[] buf = void;
That gives me a) no buffer, who's pointer is b) not initialized to null.
I want instead a defined pointer, to a valid array, that is initialized
to zero.
Anyway, I think the flaw in my proposal is the use of a GC. Since we
don't get the memory directly from the operating system, but from a
memory pool in the GC, it is generally 'recycled' and already used
memory. It has to be zeroed out manually, unless there was a way to tell
the OS to rebind some virtual memory addresses in our program to this
magic 'zero page'.
You usually don't need initialized memory from the GC.
The calloc behavior is still pretty interesting.
