Max Semenik:
Does anyone mind if I create a magic word for current user's language? It will not fragment parser cache further than it is already because we already support {{int:}}. Note that this functionality is already emulatable with perversions like http://is.gd/4HQPeI - would be good if we saved users from PITA like this.
One possibility would be for that magic word to be used on every single page, for example to localize the stub / help templates appearing at top of the page.
I guess that would destroy the parser cache entirely.
