They may not need an up to date numpy version now, but if stopping
support for them is a requirement for C++, it must be kept in mind. I
actually suspect Travis to have more details on the big iron side of
things. On the small side of things:
This may seem like not very useful - but that's part of what a open
source project is all about in my mind.

scipy.sparse.sparsetools is quite straightforward in its usage of
templates (would be great if you could suggest improvement BTW, e.g.
scipy/sparse/sparsetools/csr.h), and does not by itself use any
I like that numpy can be built in a few seconds (at least without
optimization), and consider this to be a useful feature.
