10/// ## What it does
11/// Checks for usage of the `isNull` function.
12///
13/// ## Why is this bad?
14/// `isNull` is deprecated.
15///
16/// ## Example
17///
18/// Instead of `isNull` for `null` checks,
19///
20/// ```nix
21/// isNull e
22/// ```
23///
24/// use the equality operator:
25///
26/// ```nix
27/// e == null
28/// ```
