    AssignmentExpression : LeftHandSideExpression AssignmentOperator AssignmentExpression
      1. Let _lref_ be the result of evaluating |LeftHandSideExpression|.
      2. Let _lval_ be ? GetValue(_lref_).
      ...
      7. Let _r_ be ApplyStringOrNumericBinaryOperator(_lval_, _opText_, _rval_).
      8. Perform ? PutValue(_lref_, _r_).
      9. Return _r_.

      1. Let _baseReference_ be the result of evaluating |MemberExpression|.
      2. Let _baseValue_ be ? GetValue(_baseReference_).
      3. Let _fieldNameString_ be the StringValue of |PrivateIdentifier|.
