/// ```swift
/// class X {
/// let a = 42
///
/// func (a: Int) {
/// let a = 123
///
/// a // <-- lookup here
/// }
/// }
/// ```

/// set to `false`, lookup will return declaration from inside function body,
/// function parameter and the `a` declaration from `class X` member block.
/// If `finishInSequentialScope` would be set to `false`, the only name
/// returned by lookup would be the `a` declaration from inside function body.
