Me too, but I am extremely biased toward nan is always bogus by my own
usage of numpy/scipy (I never use NaN as missing value, and nan is
always caused by divide by 0 and co).

I like that sort raise an exception by default with NaN: it breaks the
API, OTOH, I can't see a good use of sort with NaN since sort does not
sort values in that case: we would break the API of a broken function.
