This means that some additional care is needed to avoid bugs that + would be caught by the type checker in a traditional C++ program. + +- The NumPy interface ``pybind11::array`` greatly simplifies accessing + numerical data from C++ (and vice versa), but it's not a full-blown array + class like ``Eigen::Array`` or ``boost.multi_array``. + +These features could be implemented but would lead to a significant increase in +complexity. I've decided to draw the line here to keep this project simple and +compact. Users who absolutely require these features are encouraged to fork +pybind11. + |
