It may be convincing if you only consider natural numbers in ascending
order. Suppose you have the sequence a .. b and you want the reverse.
If you work with included bounds the reverse is just b .. a. If you use
the python convention, things become more complicated.

Another problem is if you are working with floats. Suppose you have a
set of floats. Now you want the subset of numbers that are between a and
b included. If you want to follow the convention that means you have to
find the smallest float that is bigger than b, not a trivial task.
