T.tuple

A collection: fixed arity, one schema per slot.

T.tuple([
  T.number.whereby({ min: 1, max: 100 }),
  T.number.whereby({ min: 1, max: 100 }),
  T.number.whereby({ min: 1, max: 100 }),
]);

For "exactly these things, in this order, each possibly a different shape." Contrast with T.array: an array has one shape repeated a fuzzed number of times; a tuple has a fixed number of slots, each independently typed and independently fabricated — each slot draws from its own private stream, the same way each field of a T.object does, so one slot's randomness never affects another's.
