add @something! for updating the first arg to something

Are there situations where this makes a problem easier to solve? I'm not entirely convinced it's worth it to save 2 ASCII characters. |

I don't like implicit variables like this, and current tooling (at least the LanguageServer stack) can't understand it since it doesn't expand macros. |
It's more of a formatting bother if the first arg has a long name, which means more than 2 chars. I hoped this would be considered reasonably standard behavior to understand/expect, indicated by the The point about tooling is fair, but alone I think it would be a shame to limit language features based on current tooling limitations. But if the concept isn't popular that point is moot. |
