Sorry for the slow reply, I had to think a bit about which approach I preferred.
Does the attached code, using transform_view do what you need?
Seems a bit nicer of a solution than what I suggested.
I'm not comfortable adding non const ctors to vector for a few reasons, so I'd prefer this approach if possible.
Still, it's just a workaround (IMHO) as it requires us to transform the whole sequence just because we can't keep it from getting const qualified. It certainly adds compile time overhead and I bet it even directly or indirectly infers code with some compilers. What about making the existing "Seq const & ctor" accept reference wrappers?
