How would you make that distinction? At this point I can imagine
students immediately thinking that my factorial program is a recipe
and wondering why it doesn't involve monads. Either you distinguish
between these things in a circular way using monads (no use when
teaching monads in the first place) or you have some a priori
distinction that you point out to students.
