Yes, it's annoying when English words can have two or more meanings. The
first time I can across math.sin, I was very excited, until I realised
it was just the trigonometric function :-(
This is the gunslinger.draw versus the artist.draw problem.
Unfortunately there can be a conflict between uniqueness and plain
English, so unless we start naming our functions using GUIDs instead of
words, we're always going to have to deal with it.

In the builtins, `range` returns a iterable sequence of integers, it
is not the statistical `range` function. `ord` stands for "ordinal", not
"order" or "ordinary". `map` doesn't return a geographical map. And
somehow we managed to cope.
