NOT.2:5.3 - Scope in a structured sequence

Suppose sequence(A, B) means perform A and then B, and repeat(n, S) means repeat S n times. Then repeat(3, sequence(A, B)) contains three performances of each action. sequence(repeat(3, A), B) contains three of A and one of B. A written delimiter, spoken grouping cue or learned gesture can carry this boundary if the receiver can reliably use its convention. The temporal realization and effort of perceiving or performing it are further questions for NOT.8.
