I think this makes sense. The disadvantage is the overhead of optional
just to do "extract"ion. I understand from the other posts that implementing
optional in terms of variant as is an overkill? If so, at least effort must be
put into making both libraries reuse as much common parts as possible.
I'm sure there are lots of commonality, right?
