}

switch foo {
    case let (x, y): break
}

switch foo {
    case .foo(let x): break
}

}

switch foo {

Triggering Examples

    case (↓let x,  ↓let y): break
}

switch foo {
    case (↓let x,  ↓let y, .foo): break
}

switch foo {
    case (↓let x,  ↓let y, _): break
}

switch foo {
    case (↓let x,  ↓let y, f()): break
}

switch foo {
    case (↓let x,  ↓let y, s.f()): break
}

switch foo {
    case (↓let x,  ↓let y, s.t): break
}

switch foo {
    case .foo(↓let x, ↓let y): break
}

switch foo {
    case (.yamlParsing(↓let x), .yamlParsing(↓let y)): break
}

switch foo {
    case (↓var x,  ↓var y): break
}

switch foo {
    case .foo(↓var x, ↓var y): break
