It'd be cool to attach metadata to string literals that doesn't end up in the resulting string object. This metadata could be used by all sorts of tools, everything from localization to refactoring. In C, some localization libraries use macros for it, such as: #define LOCALIZE(s) s and it acts like an annotation, and then you do: printf("%s", get_localized(locale, LOCALIZE("This string gets extracted and used in language files"))); And I think Python could do better and have special string literals explicitly for this purpose. It could even be something with fstrings, like: f"{#localize}This string gets extracted and used in language files" Ofc, there's nothing preventing one from using something like f"{(lambda _:'')('localize')}This string gets extracted and used in language files" today, but I feel like having some sort of dedicated syntax for it would be an improvement.
