+/// **Note:** to maintain compatibility with PyFlakes, this rule only flags
+/// f-strings that are part of an implicit concatenation if _none_ of the
+/// f-string segments contain placeholder expressions.
+///
+/// For example:
+///
+/// ```python
+/// # Will not be flagged.
+/// (
+///     f"Hello,"
+///     f" {name}!"
+/// )
+///
+/// # Will be flagged.
+/// (

+///     f" World!"
+/// )

 /// ## References
