list and dict are suported by pybind11 (just like by boost::python), but support for the set builtin type is missing (also from boost::python -- see http://thread.gmane.org/gmane.comp.python.c++/15129). Could set be supported by pybind11?

Good point -- I've committed support for std::set.

Great. For API similar to python, shouldn't insertion be called pybind11::set::add rather than insert?

fair enough -- I renamed it.

Tell cmake to use EXACT python version (from PYBIND11_PYTHON_VERSION).

This should insure that both the PythonLibs and PythonInterp points to
the same python version.

Without this, the Python library and interpreter might not match version.
For example, if both Python 2.7 and 3.4 is installed, PythonLibs will
find /usr/lib/x86_64-linux-gnu/libpython3.4m.so while
PythonInterp will find /usr/bin/python2.7 (at least on Ubuntu 14.04).

When PythonLibs and PythonInterp don't point to the same Python version,
the examples will all fail:
