I am 100% sure that they're documented, yet I am not very lucky with the docs
either.

You can reference the member function pointer like this (untested of course):
.def("bar", (void(Foo::*)(const Y*))&T::bar)
.def("bar", (void(Foo::*)(const X&,const Y*))&T::bar)

Really? AFAIK, it should work.
You should be able to write (arg("some_x"), arg("some_y") = NULL)) as
extra .def() argument.
Maybe py++ does not output the default args when the arguments are unnamed?
(I wouldn't know how, either.)
