Fernando, can we also decide if this is some useful toy we want to share with the lib world or an implementation detail?
I don't have a strong opinion or problem with regarding this as an implementation detail, but I do need to find a nice solution, like the one Anthony just proposed.
Fine.
[...] Anyway, I think none is useful outside optional<>, specifically, for variant<>, tuple<> and even any.
Please don't take this as obstructionism, but I just don't know. Really.
I take you disagree. Can you explain why?
Even if it happens to be shared between three or four libraries it still doesn't belong to the root dir just for that. You could probably agree to have it in detail/, but that's going to give problems in the long run in my opinion, probably mitigated if you insert a big comment along the lines of "Caution: this component is shared between x, y and z and shall keep the following behavior and interface. Only apply workarounds if they are needed for all of x, y and z, etc.". I'd suggest discussing that with the authors of the libraries you want to share it with. If you all agree that the benefits outweigh the cost I don't have strong objections (not that I don't have ;-)) Well, not sure I was clear enough, as it's a bit late and I spent all my energies today, so don't hesitate to ask again if you feel so. -- [ Gennaro Prota, C++ developer for hire ]
