Thank you for your answers Paul. Just a note: I have called it
interval-something (like cinterval or Interval) instead of
range-something because it returns a closed interval (all letters
inclusive of both endpoints), to show its difference from the Python
range that returns a right open interval. Calling a srange("a","z") in
Python lets me think that it generates the ["a",...,"y"] range.
