This is a curious reply for me. I would think that there are very few parts in pandas that could be sped-up by reimplementing them with a compiled language. Pandas is plenty fast for the built-in methods, it only gets slow when you start interfacing with Python, e.g. by doing an `.apply` with your custom Python method. Obviously this interfacing part is impossible to speed up by reimplementing parts of pandas (you'd need a different API instead).
