Called on a tuple (a1, ..., an), returns a new tuple (f(a1), ..., f(an)).
Called on a tuple (a1, ..., an), returns a new tuple (f(a1), ..., f(an)). The result is typed as (F[A1], ..., F[An]) if the tuple type is fully known. If the tuple is of the form a1 *: ... *: Tuple (that is, the tail is not known to be the cons type.

Given two tuples, (a1, ..., an) and (a1, ..., an), returns a tuple ((a1, b1), ..., (an, bn)).
Given two tuples, (a1, ..., an) and (a1, ..., an), returns a tuple ((a1, b1), ..., (an, bn)). If the two tuples have different sizes, the extra elements of the larger tuple will be disregarded. The result is typed as ((A1, B1), ..., (An, Bn)) if at least one of the tuple types has a EmptyTuple tail. Otherwise the result type is (A1, B1) *: ... *: (Ai, Bi) *: Tuple
