When writing Python, yes (though maybe not if you are appending a lot of
data at once from a numpy array). That's whey my python implementation
is slower, and I suspect a C implementation would be similar in
performance to a list.
But if you are writing a C extension in C or Cython, then you could get
a real gain by not having to go through Python types.
