Overriding a class with py::new_ from Python

[smurfix]

When I have some custom __new__ methods in my class …

        py::class_<TileIndex>(m, "Tile_")
            .def(py::init_implicit<uint32_t>())
            .def(py::new_([](unsigned int xy){ return TileIndex(xy);}))
            .def(py::new_([](unsigned int x, unsigned int y){ return TileXY(x,y);}))
            ;

… how do I create a subclass in Python?

from tile_cpp import Tile_

class Tile(Tile_):
    pass
print(type(Tile()))

… emits "Tile_", apparently because Python sees the special __new__ which (as documented) ignores its class argument.

The docs says that I can write a static __new__ that gets the class, but how do I then magick my instance it into existence?

Does PR #859 address your issue?

[smurfix]

It should. Not yet tested but I will do that shortly.

Update: Yes it does. It also makes my A* pathfinder three times faster. Thanks @oremanj !

I merged it.
