pybind11 strives to be a general solution to binding generation, but it also has certain limitations:
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.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.
