Description
Assume I have class/struct Foo and operator std::ostream& operator<<(std::ostream&, const Foo&). In Boost.Python, one can use something like:
.def(str(self))
to enable the use of print(foo) from Python. See discussion here.
Currently, I'm only aware of the following usage to get print(foo) to work using pybind11:
.def("__str__", [](const Foo& self) { std::stringstream ss; ss << self; return ss.str(); })
I wonder if there is a more convenient way of doing this already in pybind11.

Research direction
No repository file or test is named. Start by examining the .def(str(self)) Boost.Python pattern, the str lambda workaround, and pybind11's .def binding entry point; done means a convenient way for print(foo) to use Foo's operator<<, with the behavior covered by a test.
