Why? I don't agree with this at all. I actually expect tuples DON'T have
The thing my DIP talks about are things that don't have struct semantics...
what is that called?

Make a DIP then. I don't like that idea. It's problematic to know if you
are dealing with a kind of thing that can be unrolled until much later in
semantic when it should have already been done.
It's trivial to implement a static unroll: `MyList[iota!(MyList.length)]...`
Which can easily become: `alias StaticUnroll(T) = T[iota!(T.length)]...`
