=== Exceptions

|
|
Blocks in an `if` chain that contain a single line of code are ignored, as are blocks in a `switch` statement that contain a single line of code with or without a following `break`.

But this exception does not apply to `if` chains without `else`-s, or to `switch`-es without default clauses when all branches have the same single line of code. In the case of `if` chains with `else`-s, or of `switch`-es with default clauses, rule S3923 raises a bug.
