I think you need to write

Thanks as always Joaquin, this solves the compilation error. I might have misunderstood how hashed indices work, because I don't know if multi index is suitable for fast retrieval of, for instance, all 128-bit integers that have MSB equal to 3? Something akin to a simple std::unordered_multimap with better storage? It's a fairly complex library, I must admit :) Thanks!
