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.
