I have an idea for a shortcut for interlinks --
could an interlink with no article name be taken to mean "the same title
as this page"?
eg:
On the french page "Milan Kundera", a link that's just "[[en:]]
would mean "the equivalent english language page has the same name, ie
it is [[en:Milan Kundera]].
(... or is this one of those cool things the dev team have already
thought of but not told us mortals? ;-)
