I would be very interesed in knowing which incompatibilities among the
different hash_maps have given you trouble (constructors? hash functions?
etc.). And when given two or more different interfaces for a particular
compatibility issue, which you prefer and why. I know that there are
incompatibilities, but I also know that there are many similarities.
What I don't know is which incompatibilities are serious, and what (if
anything) is missing from all of the hash_map's that you have tried.
