What if NumPy and SciPy were part of the Python stdlib--would this change your view at all? (Note that for the majority of Python's scientific users, this might as well be the case, since they're using Anaconda to get their Python distribution set up.)

Like I mean sure, maybe it'd be nice to have some syntactic sugar at the language level for tensors (though IMO the slice syntax for numpy.ndarray is already plenty), and maybe it's a microannoyance to have to write `import numpy as np` over and over, but what else is lacking?
