-/// ## What it does
-/// Checks for implicitly concatenated strings inside list, tuple, and set literals.
-///
-/// ## Why is this bad?
-/// In collection literals, implicit string concatenation is often the result of
-/// a missing comma between elements, which can silently merge items together.
-///
-/// ## Example
-/// ```python
-/// facts = (
-///     "Lobsters have blue blood.",
-///     "The liver is the only human organ that can fully regenerate itself.",
-///     "Clarinets are made almost entirely out of wood from the mpingo tree."
-///     "In 1971, astronaut Alan Shepard played golf on the moon.",
-/// )
-/// ```
-///
-/// Instead, you likely intended:
-/// ```python
-/// facts = (
-///     "Lobsters have blue blood.",
-///     "The liver is the only human organ that can fully regenerate itself.",
-///     "Clarinets are made almost entirely out of wood from the mpingo tree.",
-///     "In 1971, astronaut Alan Shepard played golf on the moon.",
-/// )
-/// ```
-///
-/// If the concatenation is intentional, wrap it in parentheses to make it
-/// explicit:
-/// ```python
-/// facts = (
-///     "Lobsters have blue blood.",
-///     "The liver is the only human organ that can fully regenerate itself.",
-///     (
-///         "Clarinets are made almost entirely out of wood from the mpingo tree."
-///         "In 1971, astronaut Alan Shepard played golf on the moon."
-///     ),
-/// )
-/// ```
-///
-/// ## Fix safety
-/// The fix is safe in that it does not change the semantics of your code.
-/// However, the issue is that you may often want to change semantics
-/// by adding a missing comma.
