    1. Let keyResult be the result of performing ? ForIn/OfHeadEvaluation(« »,
       AssignmentExpression, iterate).
    2. Return ? ForIn/OfBodyEvaluation(LeftHandSideExpression, Statement,
       keyResult, assignment, labelSet).

    [...]
    4. If destructuring is true and if lhsKind is assignment, then
       a. Assert: lhs is a LeftHandSideExpression.
       b. Let assignmentPattern be the parse of the source text corresponding to
          lhs using AssignmentPattern as the goal symbol.

       d. If IsAnonymousFunctionDefinition(Initializer) is true, then
          i. Let hasNameProperty be HasOwnProperty(v, "name").
          ii. ReturnIfAbrupt(hasNameProperty).
          iii. If hasNameProperty is false, perform SetFunctionName(v, P).
