--- Comment #6 from Roy Stogner <roystgnr at ices dot utexas.edu> --- Copyright assignment shouldn't be a problem. The one serious non-technical problem is going to be finding time to work on a patch. The only technical issue I've discovered so far is that making this robust with no efficiency penalty seems to be impossible without operator overloads that take rvalue references. libstdc++ policy is that C++11 features are fine to use if wrapped in #if __cplusplus >= 201103L and C++03 compatibility is maintained?
