Inspection for `<>` between curly braces without named symbols?

[dnbln]

error: Using `<>` between curly braces (e.g., `{<>}`) only works when your parsed values have been given names (e.g., `<x:Foo>`, not just `<Foo>`)

Yeah, that makes sense because that expansion looks like this (with names):

{ x: x }
// or equivalently just
{ x }
