Hi Gwern, I'd say abandoned prototype at this stage. I no longer work on Yhc, no longer have a working copy, and don't have permission to push patches. I wouldn't bother going to any effort cleaning it up, unless you want to maintain/improve it in the long run. That said, when I last used it, it certainly did parse case expressions/lambdas! It was basically Haskell 98 plus a couple of extensions, but not that much of the base library. I've no idea if you broke something in your cleanup, or if something else got broken before you got to it. Thanks, Neil On Mon, Mar 8, 2010 at 10:09 PM, Gwern Branwen wrote:

I was trying to remove the haskell98 dep, but after I had apparently gotten rid of most, I began running into all sorts of odd syntax errors - missing \ in lambdas, = in case expressions, list syntax in type sigs - that I've begun to wonder if that is a real compiler or an abandoned prototype or something.
