is a pattern object that represents a sequence of one or more expressions, each matching p.

Repeated

Repeated

represents between min and max expressions matching p.

p.. can appear as an argument of any function. It represents any sequence of arguments.

All the objects in the sequence represented by p.. must match p, but the objects need not be identical.

The expression p may, but need not, itself be a pattern object.
