1Limitations 2########### 3 4pybind11 strives to be a general solution to binding generation, but it also has 5certain limitations: 6 7- pybind11 casts away ``const``-ness in function arguments and return values. 8 This is in line with the Python language, which has no concept of ``const`` 9 values. This means that some additional care is needed to avoid bugs that 10 would be caught by the type checker in a traditional C++ program. 11 12- The NumPy interface ``pybind11::array`` greatly simplifies accessing 13 numerical data from C++ (and vice versa), but it's not a full-blown array 14 class like ``Eigen::Array`` or ``boost.multi_array``. 15 16These features could be implemented but would lead to a significant increase in 17complexity. I've decided to draw the line here to keep this project simple and 18compact. Users who absolutely require these features are encouraged to fork 19pybind11. 20 21
