Numpy is not Python, but a specialist third-party package that has made specialist choices about basic operations --
that does not sound like a shortcoming of the language.
It seems to me that the appropriate fix is for numpy to have an "is_empty()" function that knows how to deal with arrays
and array-like structures, not force every container to grow a new method.
