Yes, you’re right.  Having the compiler type-check parts of all your
program is a win, no doubt about it.

Nevertheless, type safety can be viewed as one of the many properties of
a program one could want to prove or test.

Did you know that Coq would only compile a function when it can prove
that it terminates?  That’s another kind of compiler-supported proof one
quickly gets used to.

Thanks,
Ludo’.
