Does adding type annotations fix the problem? Why do you think this warning is unexpected here?

[kerams]

Because I am not using objects anywhere. The fact that PrintfFormat has a bunch of type parameters is an implementation detail (formats are an intrinsic), so I don't see why I should be warned if some of them are inferred to be obj.
