I tend to agree with that.

On the other hand, numpy itself is kind-of sort-of statically typed. But in that case, if you need to know the type of an array -- check the array's dtype.

Also:

I Never liked declaring numpy arrays with the python types like "int" or "float" -- in numpy you usually care more about the type, so should simple use "int64" if you want a 64 bit int. And "float64" if you want a 64 bit float. Granted, pyton floats have always been float64 (on all platfroms??), and python ints used to a be a reasonable int type, but now that python ints are bigInts in py3, it really makes sense to be clear.

And now that I think about it, in py2, int is 32 bit on win64 and 64 bit on *nix64 -- so you're really better off being explicit with your numpy arrays.
