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!
