In addition, it removes most of the stuff that's specific to the C++ APIs - so it should correspond pretty well with what you can discover by experimenting in a Python interpreter session. It must be said though, that it's by no means perfect (which is hardly surprising, given that it's probably all  generated automatically).

But I still think that PyQt should provide a complete Python-specific API Reference if it can. All that's needed is something very much like the current PyQt4 Class Reference, only without all the redundant explanatory material (links to the current Qt docs would actually work much better). This would make the task of translating between the two APIs a great deal easier - a PyQt Rosetta Stone, if you like. Maybe this is something that the type-hinting support will eventually make possible?

Yes, that's the plan. I intend to take the documentation (and probably the examples) out of PyQt5 and make them a separate package so that they can have more frequent releases.
