Does Jhc currently support pattern-guards, or is one of us going to have to implement that? And does Jhc support LANGUAGE pragmas (or just as good for me, ignore them and use all its extensions all the time)?
you know, for my crazy idea of compiling ghc 6.9 sometime soon :-)
No, pattern guards are currently not supported. which is too bad, as they are perhaps one of my favorite extensions. Jhc currently doesn't support the LANGUAGE pragma, but it should be pretty trivial to add it. FrontEnd.Syn.Options is a small module that just searched for pragmas near the beginning of the file, in Ho.Build it is called to extract the OPTIONS pragmas, you can easily extract the LANGUAGE and CHARSET pragmas there as well and modify the behavior appropriately. all that would be needed is a lookup table of LANGUAGE option to 'Option' parameter.
