I am not exactly sure what you are after with this or your previous post
about tuples. Tuples are 'type safe' for any definition of 'type safety'
that I can summon. Switching over tuples to restructure them is, in my
opinion, a main source of the type safety provided in tuples. I do hope
that, along with conditional conformance and the ability to add extensions
with self same types, we get the ability to define extensions on tuples.
These features would allow us more convenience when dealing with tuples and
might possibly ease the woes that you are presenting.
