The only way I've seen xtensor used is *with* pybind11

Hi Sylvain,

Actually, xtensor-python does a lot more in terms of numpy bindings, as it uses the C APIs of numpy directly for a number of things.
Plus, the integration into the xtensor expression system lets you do things such as view / broadcasting / newaxis / ufuncs directly from the C++ side (and all that is in the cheat sheets).
ok, good, but my point was different. The page in question is about Python as a glue language. The other solutions on that site are general purpose binding solutions for any kind of C++ code, while xtensor-python is xtensor-specific. xtensor in turn is a library that mimics the numpy API in C++.
Even if you don't use the numpy-mimicking parts of the xtensor API, xtensor-python is a probably a net improvement over pybind11 for communicating arrays back and forth across the C++/Python boundary. Even if the rest of your C++ code doesn't use xtensor, you could profitably use xtensor-python at the interface. Also, though the article is generally framed as using Python as a glue language (i.e. communicating with existing C/C++/Fortran code), it is also relevant for the use case where you are writing the C/C++/Fortran code from scratch (perhaps just accelerating small kernels or whatever). Talking about the available options for that use case is perfectly on-topic for that article.
You don't have to be the one that writes it, though, if you just want to cover pybind11.
