I'd like to use an infix'ed operator in a chain of higher-order functions.  But when I do, I get told that`it` is nullable; even when I explicitly check:
```
    var nums = args.map { parseInt(it) }
            .filter { it != null }
            .map { it * 2 }
```
generates the compiler error: "Infix call corresponds to a dot-qualified call 'it.times(2)' which is not allowed on a nullable receiver `it`. Use ?.-qualified call instead."
