Functions that are overloaded with one version taking no arguments and another taking only some number of Void arguments would break, but I'm not sure how important that is. Nor am I sure that's all that would break. I'm mean, really we'd just be automatically adding functions that only have Void arguments to the call-site "func foo() {}" vs "func foo(x: SomeType = someValue) {}" issue.

Meh, maybe such implicit behavior should be reserved for "Never", if we ever get that.
