[Numpy-discussion] Warnings as exceptions?

[Michael McNeil Forbes]

Why are numpy warnings printed rather than issued using the standard  
warnings library?  I know that the behaviour can be controlled by  
seterr(), but it seem rather unpythonic not to use the warnings library.

Is there an explicit reason for this choice?  (It seems like a pretty  
trivial modification of util.py will catch most of the cases.)  If  
performance is an issue, one could add a 'print' mode which behaves  
as the current 'warn'.

Michael.

(P.S. I am sure this has been discussed somewhere before, but I can't  
seem to find a reference.)
