I second that. This is the way mathematicians use the
word "where", and it would be a much better way of
spending a keyword.

Indeed. Also, the situations where you can meaningfully
test each function on its own using a few concisely-
expressed test cases are relatively rare, IMO. It
looks good for the kind of exercises you find in
programming courses, but it doesn't scale up to
real-life code that requires complex data structures
and test harnesses to be set up.
