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...
