Is this by design, or just an unfortunate legacy? I would've expected
(obviously wrongly) that the core classes provide and support all the
functionalities of properly registered custom types.
And a follow up question: I'm not intimate with the internals, so is it
feasible to actually bring this to consistency and have the stream
operators registered in the meta-type system for the core classes?
