META-PROPOSAL: Documentation should be required to say when exports were introduced

Hi all, This is trac #1903: http://hackage.haskell.org/trac/ghc/ticket/1903 One of the nice things about, for example, PHP is that if you look at the documentation for one of its functions, e.g. http://www.php.net/manual/en/function.file-get-contents.php it tells you that file_get_contents is available in PHP >= 4.3.0. I propose that all exports in Haskell libraries should be required to have such a thing in their haddock documentation. For the current code we could either give the current versions as the date of introduction, or do some digging and put precise data in. Initial deadline: 1 December 2007. Thanks Ian
