error: dependency loop detected
const Node = Wrap(usize, ?*Node);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
a workaround for this bug is to use:
const Node = Wrap(InnerType, ?*opaque {});
*opaque{} is a generic pointer, you can put anything in, but to get out a *Node you need to cast:
const node: ?*Node = @ptrCast(@alignCast(tail))
