why do you think separate compilation

Because of type inference over recursive module imports. Determining
the type of a function may, in general, require inferring types

Consider this:

I think I see what you're saying. I still maintain, however, that,
since you've changed the type of B.b (admittedly implicitly), and B.b is
exported from B, that you've changed B's interface.
There is a reason make is
