Which std.trait should be used to statically check whether I
should call GC.{add,remove}Range on the elements of D containers?
`std.container.array.Array` currently uses `hasIndirections` but
a comment on the same line says it should use `hasPointers`
instead.
containers-em uses
template shouldAddGCRange(T)
{
import std.traits;
enum shouldAddGCRange = isPointer!T || hasIndirections!T || is
(T == class);
}
Quite some inconsistency here.
And what the case `Array!(Array!int))`? The wrapper Array!int
contains contains a non-GC allocate pointer to ints and should
not be scanned by the GC. Do we need another Container-trait for
this? Or do we need to tag pointers with a special attribute that
tells whether it has been allocated by GC or not.
