we might concievably want to build such a massive tuple as part of the

</p><p>We call tuples above this size "big tuples", and emulate them by
creating and pattern matching on >nested< tuples that are expressible
by GHC.

than a 10-tuple of 2-tuples (11 objects), so we want the leaves of any
construction to be big.
