I've been avoiding void[] for this reason (I mean, void[]

If I do:
ubyte[] arr = new ubyte[100_000_000];
void[] arr2 = cast(void[]) arr; // will this still avoid
scanning?
Does the GC still know that this area is NO_SCAN?
Yes (as per Adam's post).
However, it's easy to lose it with operations like concatenation
or appending. `a ~ b` will allocate `void[]` (without `NO_SCAN`)
if either are `void[]`. This is why I still use `ubyte[]` (or, in
ae, `Data` / `DataVec`) for raw data.
