I'd be ok with something like allvars() and requiring a dictionary to the .sub() method, /if/ allvars() were a method on a frame object. I really, really do want to write in my i18n programs: def whereBorn(name): country = countryOfOrigin(name) return _('$name was born in $country') I'd be fine if the definition of _() could reach into the frame of whereBorn() and give me a list of all variables, including ones in nested scopes. Actually, that'd be a lot better than what I do now (although truth be told, losing access to nested scoped variables is only a hypothetical limitation in the code I've written). The feature would be useless to me if I had to pass some explicit dictionary into the _() method. It makes writing i18n code extremely tedious. Invariably, the unsafeness of an implicit dictionary happens when strings come from untrusted sources, and your .py file can't be considered untrusted. In those cases, creating an explicit dictionary for interpolation is fine, but they also tend not to overlap with i18n much. -Barry
