description: Left-hand side as a MemberExpression
info: >
    AssignmentExpression[In, Yield] :
        LeftHandSideExpression[?Yield] = AssignmentExpression[?In, ?Yield]

    1. If LeftHandSideExpression is neither an ObjectLiteral nor an
       ArrayLiteral, then
       [...]
       e. If IsAnonymousFunctionDefinition(AssignmentExpression) and
          IsIdentifierRef of LeftHandSideExpression are both true, then

          i. Let hasNameProperty be HasOwnProperty(rval, "name").
          ii. ReturnIfAbrupt(hasNameProperty).
          iii. If hasNameProperty is false, perform SetFunctionName(rval,
               GetReferencedName(lref)).
