Not at all! The PyBuffer library is all about interfacing to C data. As far as I know, creating a (mutable) contiguous array of floats is impossible in the Python language. This seems to be a deliberate language design decision.

My point exactly. The "array" class cannot be implemented in Python.

Uhh, so: Python has a language library feature that allows creating contiguous arrays, and hence it cannot be done in Python. Ok.

// Pretty much the entirety of CPython is written in C, including lists, dicts and everything else, not much different than the array.
