    IterationStatement :

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

    [...]
    5. 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.

    AssignmentElement[Yield] : DestructuringAssignmentTarget Initializeropt
    [...] 6. If Initializer is present and v is undefined and
       IsAnonymousFunctionDefinition(Initializer) and IsIdentifierRef of
       DestructuringAssignmentTarget are both true, then
       a. Let hasNameProperty be ? HasOwnProperty(rhsValue, "name").
       b. If hasNameProperty is false, perform SetFunctionName(rhsValue, GetReferencedName(lref)).
