+ДЗ 4 (Конструкции управления):
+
+* Написать синтаксический анализатор для- и поддержать в режими интерпретации конструкции потока управления `if`, `while`, `for`, `repeat ... until`
+* `if...elif...[else ...]?` и `for` должны быть реализованы как синтасический сахар
+* `repeat ... until` необходимо поддержать на уровне абстрактного синтаксиса
