There's the option of stating everything in terms of boost::yap::tuple 
instead, which today would be an alias to hana::tuple. It's questionable 
exactly how much this will help users in the event of moving to std::tuple, 
but it might be possible for at least some user code to not need changes.

On a completely unrelated note, have you considered the use case in which an 
expression supports two separate modes of evaluation? yap::evaluate doesn't 
take a "mode" parameter, and the way it's specified makes it hard to extend 
it with one.
