If you're using dicts as dicts, Cython just uses the CPython ones via
the C API, rather than defining its own.

I didn't do any specific research for C++ (since it's essentially the
king of fast low level data structure design, hence its popularity in
graphics programming), but did see a few references to C++ ordered
hash map implementations while looking into the available options for
other runtimes.

Cheers,
Nick.
