Hi Ian,
Yes, this is now
http://haskell.org/ghc/docs/latest/html/libraries/base-4.2.0.0/Prelude.html#... ~~~~~~~~~~~~
I'd suggest that Hoogle shold probably use its own copy of the docs, so that it stays in sync with them. Also, you probably want to index the set of libraries that come with the Haskell Platform, rather than just those that come with GHC.
Too late. We had a stable link, I used it, Google used it, blog posts were written that linked to it, I've emailed my wife links to it, I've put them in Word documents, I've posted them on internal intranets. You can't create a link, put content behind it, then move the content - it just breaks the whole web. I can fix Hoogle, but I can't fix the rest of the web... I recommend putting in a permanent redirect from where the old docs used to be to base 4.0, and then never moving it forward. Or perhaps symlinking latest to always the latest version. Either way, I think breaking a huge set of links is a really bad idea. I also think it's a bad idea for Hoogle to link off to different documentation from the rest of Haskell, it's just not a good idea to fragment the Hoogle universe from the rest of the docs. Thanks, Neil
