If we're talking about constructing structs, like in `Foo { bar, baz: 123 }` (with the `bar` style shortcut in it), I have used that kind of syntax 10 times in 16 KLOC of Rust. Not a lot, but it does happen, and I found it kinda neat when LSP integration suggested its use. I've probably used it more for pattern matching (`let Foo { bar, baz } = ...`), but haven't measured the number of instances of that idiom.
