Far from it.  You've extrapolated a lot more than what I actually
said, and I completely agree with everything you wrote.  I was
explaining EAFP as I see it, not advocating it for all circumstances.

Although since you bring it up, I find that the LBYL crowd tends to be
more prone to exception avoidance, e.g. returning None on a failure
rather than raising an exception, whereas the EAFP crowd seems more
likely to just let the original exception propagate up.
