Any idea why then is an infix function but thenBy isn't?

Declare a function as infix only when it works on two objects which play a similar role. Good examples: and, to, zip. Bad example: add.

Comparator then Comparator has both objects playing similar roles, Comparator.thenBy(selector) does not

I see. So Mockk blatantly ignores this guideline with all its infix functions like every { foo() } returns 0

mockk isn't the only DSL that breaks conventions, but stdlib (non-DSL) interfaces do try to promote standard style
