I find this persuasive, even though I am unhappy that it
means a standard Python behavior will disappear. What's
more, if the SciPy community should ultimately change its
mind, it looks easy to back out of raising an error while
hard to back out of accepting the standard behavior. So it
seems the right way to go now as long as the ultimate
outcome is in doubt.
