Re: Idiomatic import for SciPy

Thanks Pamphile.

I just wanted to chime in and note that the introduction of lazy loading
has (IMO) been a huge usability improvement. I personally now use `import
scipy as sp` in code that I write and libraries that I contribute to like
networkx have also adopted this pattern. The main reason that NetworkX has
adopted this pattern is to ensure consistency and explicitness in the code
base. For example, in networkx we have references to at least 4 different
`linalg` packages: `numpy.linalg`, `scipy.linalg`, `scipy.sparse.linalg`
and `networkx.linalg`. We now always refer to these explicitly from the
top-level package alias, i.e. `np.linalg`, `sp.linalg`, `sp.sparse.linalg`
etc.

This is of course only one of many possible access patterns, but the
introduction of lazy loading made this much more convenient!
