Tuples in Verse

A tuple is a grouping of two or more expressions that is treated as a single expression.

The elements of a tuple are in the order you insert them into the tuple, and you can access the elements by their position in the tuple, called their index. Because the expressions in a tuple are grouped, they can be treated as a single expression.

The word tuple is a back formation from quadruple, quintuple, sextuple, and so on. Compare to array.

A tuple literal has multiple expressions between (), with the elements separated by commas:

(1, 2, 3)

(1, 2, 3)
