me too -- I'm sorry, I wasn't clear -- I'm not going to write any code 
that returns a zero for a missing value. These are the options I'd consider:

1) Have the user specify what to use for missing values, otherwise, 
raise an exception

2) Insert a NaN for floating points types, and raise an exception for 
integer types.

what's not clear is whether (2) is a good idea. As for (1), I just don't 
know if I'm going to get around to writing the code, and I maybe more 
kwargs is a bad idea -- though maybe not.

Enough talk: I've got ugly C code to wade through...
