10/// ## What it does
11/// Checks for binds of the form `inputs @ { ... }` in function
12/// arguments.
13///
14/// ## Why is this bad?
15/// The variadic pattern here is redundant, as it does not capture
16/// anything.
17///
18/// ## Example
19///
20/// ```
21/// inputs @ { ... }: inputs.nixpkgs
22/// ```
23///
24/// Remove the pattern altogether:
25///
26/// ```
27/// inputs: inputs.nixpkgs
28/// ```
