There was a problem hiding this comment.
Не, так не работает: в \psi ничего не меняется, кроме переменной x. Поэтому, что бы мы ни подставили, ни одно свободное вхождение не станет связанным.
Я дал здесь общее определение, поэтому может показаться требование свободы для переменных из \theta избыточным (в терме все предметные переменные свободны). Но в лямбда-выражениях это требование становится существенным.
