Yes, I read about that, but I consider it a hack, not proper support.
Since CamlIDL considers Foo completely opaque and doesn't even see that
it is a pointer, I cannot use pointer-specific attributes such as [ref],
[unique] and [ignore]. And saying that a type is void* when it really is
Foo* isn't even strictly legal, the way the stubs are implemented:
though conversion between void* and T* is legal for all object types T,
conversion between void** and T** isn't, yet this is the sort of type
punning that the generated stub code does.
