This is relevant. I've read the PEP and was not aware of such a wide open door. It allows building collections of string formats. Why not makes them public? Why not e.g. start a wiki page for common useful formats? Why not then store them into a standard module?

I see loads of uses in the sole field of UI.
"Please, enter a {0}."
"Hello, {0}! Ausgeschlafen? Press enter to continue..." (slept well?)
"name: {0} -- phone:{1} -- email{2}"

la vida e estranya
