| For Java convenience, methods, including `var`s and `val`s, defined directly in a singleton object also have a static method defined in the companion class, called a *static forwarder*. Other members are accessible via the `X$.MODULE$` static field for `object X`. | ||
| `static` members in Java are modeled as ordinary members of a companion object in Scala. |

@som-snytt I think this is a very important concept, and there are several deletions that explain how people can encode statics in Scala 🤔 Do you think it's reasonable that we emphasize it more in the new section?

Sorry for the late reply. Re-reading the diff, I see that static forwarding is defined on the next line 110. I'm not sure if it's less visible in the diff, or if it really needs more words.

I did that thing where the snap is to some guy who pitches it forward to the QB. I have no idea what I'm doing, but I deleted the spurious file from the old contribution and amended my commit text. I think static forwarders are adequately addressed, but no doubt someone might like to add more words later. |
