It’s talking about how you can type

  def frobQux(Qux qux, int radians) {

And it goes and reads your code and suggests a reasonable way to frob a qux a certain number of radians. Which is at the same time (a) pretty useful!, (b) fairly new, we’ve only been able to do this since 2023 or so, but (c) also not that hard by 2026 standards because capabilities have advanced so much in the last three years.
