That's reasonable, but I think in the current state of things I'd like the
user to know as soon as possible that Hana is in play. If std::tuple is
the tuple of choice, I'd probably want the user to know that up-front as

More than that, it's effectively impossible. The idiomatic way to
accomplish the same end is to transform() your expression differently for
each case, instead of evaluating it differently.
