reading the thread again from jan 11
[Numpy-discussion] TypeError: 'module' object is not callable

I'm still not clear what was going on.

The import into the sparse.linalg namespace was missing only for 2
months, after ARPACK had been temporarily removed, between r:5154 and
r:5527,   which it looks like was just when 0.7.0 was branched.

I think I added the import in 5527 just to restore the previous state.
I don't think this was an intended change in behavior.
