Do you really > believe this could lead to a non-minor problem? Yes. There are third-party packages out there that do unimaginable things when the user is prompted to enter his/her choice of something. And in any case, we don't want to rely on luck in these matters, IME the Murphy laws are very strong here. > > Using a text property for this is easy and mostly boilerplate, and it > > completely avoids this issue. > > Then I wonder why this did not happen earlier (and wonder when it will > happen).

It didn't happen for the usual reasons: no one felt motivated enough to sit down and do it. Can I convince you to try implementing this via text properties? The code will be very simple, I promise. And we are here to help if you are unsure how to go about that. > > I already explained why your design is problematic. And so did Stefan. > > No, Stefan helped me to improve my design. He did both.
