[Numpy-discussion] add xirr to numpy financial functions?

[Pierre GM]

Sorry to jump in a conversation I haven't followed too deep in  
details, but I'm sure you're all aware of the scikits.timeseries  
package by now. This should at least help you manage the dates  
operations in a straightforward manner. I think that could be a nice  
extension to the package: after all, half of the core developers is a  
financial analyst...
