I think this is the best compromise, if we can make it work.  The 
flexibility of fused types is a major plus.  Adding a general user-end 
dependency on cython would be a mistake, IMHO (scipy can be difficult 
enough to build as it is).  This would also allow us to depend on 
bleeding-edge cython versions for development builds, and hopefully fix 
some of the by-hand patching issues we've seen in the past.
