Well, it's a bit more subtle for Hana, because we can have both runtime and
compile-time sequences. For example, it could happen that one uses a 
`hana::tuple` as a parameter of a function at an ABI boundary. 

If I decide to change the layout of `hana::tuple`, which is highly plausible
for different reasons, I could break that client. I'll have to consider
this.
