Whoops... I overlooked this post - now we have a duplicate answer.

Seems a bit nicer of a solution than what I suggested.

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?
