In your divide-by-zero example, a beginner will find that
an "and" is less safe, but if "and" was an "and then", the
same beginner would not understand why "f and g" does not
work properly, where "f" and "g" have side-effects.
You should invent an "Ada for beginners" with "and also",
"and then" operators but no "and" ! Good luck...
