Limitations
###########
pybind11 strives to be a general solution to binding generation, but it also has
certain limitations:
- pybind11 casts away ``const``-ness in function arguments and return values.
This is in line with the Python language, which has no concept of ``const``
values. This means that some additional care is needed to avoid bugs that
would be caught by the type checker in a traditional C++ program.
- Multiple inheritance relationships on the C++ side cannot be mapped to
Python.
- 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``.
All of 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.
