I ask for permission to merge this change to the master of Boost.Histogram: https://github.com/boostorg/histogram/commit/90882ac086e8cec2a369c77c78f38d6... boost::histogram::axis::variant is using boost::variant internally as an implementation detail (we want to be able to change it in the future). While working on the Python wrapper for Boost.Histogram, an ambiguity was discovered in the visit function in this design. The ambiguity is resolved by using composition instead of private inheritance, which also simplifies the code. Best regards, Hans
