Yes, I see what you are saying.

I guess, it is just my use case. I need to provide a tuple-like access to
structures, not necessarily as simple as aggregates. I want to do it in a
way that requires as little of additional typing as possible. Now it looks
like the only way to do that is to provide a third library on top that
would delegate either to FPR or Describe as needed...
