This made me think of one of my favorite observations.

You occasionally hear how the wonderful static type system just forces
your program to be correct: if they compile, they work.  We all know
that this is an exaggeration, but there is one case when this seems to
apply - when refactoring already working code.

IME, it seems that whenever I tear my programs apart, as long as the
type checker agrees the pieces all fit back together, the program works
as i expect it to.

(Perhaps not so easy to apply this to a tutorial setting?)
