Why is that ?
My understanding is that a void[] doesn't have a distinct type
but since the length is bytes and not elements this makes me
believe that under the hood they are byte arrays - or, rather,
managed chunks of memory.
How's copying memory without a distinct type different from
copying, say, an ubyte[] to an ubyte[] ?
The compiler doesn't complain about that in @safe code:
```d
@safe void copy_voidA_to_ubyteA(in void[] s) {
ubyte[] d;
d.length = s.length;
d[0..$] = cast(const ubyte[])s[0..$];
}
copy_voidA_to_ubyteA([1,2,3,4]);
```
But what if I copy pointers into an ubyte[] ?
void[] are scanned by the GC but ubyte[] aren't.
