No, they are complete weirdos called USERS.  Have you ever met any?

At last you manage to get something correct, I do not get your obsession 
with run time speed.  For the fifth time, the vast majority of users 
simply do not care.  If it is fast enough, job done.

I have dealt with some complete dumbos in the years that I've been 
online, but when it comes to thickos you're right up there with the RUE, 
and I can assure you that this is meant to be an insult.

To your way of thinking run time speed is the sole issue with 
programming, and trivial details like accuracy are irrelevant. "Look, 
Python has taken a whole minute to process this data, but BartC has done 
it in one nanosecond". "Yes, but Python is 100% accurate, BartC is 100% 
inaccurate". "Who cares, only speed counts".

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.
