Repeats the given sub rule r the given number of times. Both bounds of the range must be positive and the upper bound must be >= the lower bound. If the upper bound is zero the rule is equivalent to MATCH.

Resulting rule type is Rule0 if r == Rule0 Rule1[Seq[T]] if r == Rule1[T] Rule[I, O] if r == Rule[I, O <: I] // so called "reduction", which leaves the value stack unchanged on a type level
