Includes all tuple headers.
A tuple is a fixed size collection of elements.
In the preprocessor library, tuples are represented like macro parameter lists. Thus an element of a tuple can be any sequence of tokens that constitutes a single macro parameter.
Examples of tuples:
(const, volatile) a 2-tuple (*, /, %) a 3-tuple (1, "2", '3', (4,5)) a 4-tuple
Tuples can be used for representing structured data.
