I agree that contract inheritance is an important use case, but FWIW, I write contracts in my non-class methods all the time. They are useful to document to the user (i.e., me 3 months later after I forgot the details of the code) what exactly the function expects / assumes, and for catching accidental wrong usages. Coupled with judiciously crafted unittests, this is invaluable for weeding out bugs in my code both during coding and also prevents regressions / future wrong usages of the function later.
