Cool! Sorry, I don't have the expertise to help with the boost.build
aspect, but I did have some questions and comments regarding the feature.
Does this add a dependency of boost.python on numpy? We'd love to be
able to continue use boost.python without a numpy dependency. We did a
nontrivial amount of work to remove this dependency in USD (openusd.org,
https://github.com/PixarAnimationStudios/USD), a C++ library that
provides python bindings via boost.python, so adding it back would be a
problem for us.
Instead of depending on numpy, we made our array structures implement
the python buffer protocol. This lets clients that wish to use numpy do
so easily, since numpy supports the buffer protocol, but it does not
burden those that don't with the numpy dependency. We did this manually
of course but supporting the buffer protocol would be a cool feature for
boost.python.

Hello,
I'm happy to announce that I just merged the NumPy C++ wrappers from
https://github.com/ndarray/Boost.NumPy into Boost.Python's development
branch. (Online documentation for it can be browsed here:
http://boostorg.github.io/python/develop/doc/html/numpy)
I'd very much like to be able to merge this into the master branch for
the next Boost release (version 1.63).
At present I'm using SCons to build Boost.Python (stand-alone, against a
separately installed Boost), which is also the infrastructure I use for
CI testing (https://travis-ci.org/boostorg/python).
I would like to ask for help with integrating the new NumPy extension
into the Boost.Build-based build system, such that this will also be
picked up by the regular Boost infrastructure. Please refer to
https://github.com/boostorg/python/issues/89 if you'd like to help with
this.
Many thanks !
Stefan
