Why in the world does it scare you away.  This makes no sense to me.   
If you don't like the scipy version don't use it.   NumPy and SciPy are 
not the same thing.

The problem we have is that the scipy version (0.3.2) already had this 
feature (and Numeric didn't).   What is so new here that is so scary ?
