What is the general attitude in the Haskell community towards compiler-specific extensions? My past experience with Fortran and C/C++ tells me to stay away from them. Portability is an important criterion for me.
It depends which ones. Some are implemented in multiple compilers in a consistent way and widely liked and used, and are rather likely to make it into the next standard version of Haskell in much their current form. (For instance, portability is an important criterion for us, too, but we still use multi-parameter typeclasses.) Others are still sufficiently experimental that ideas really are just being played with. It would be interesting to see a list of what people think will make it into Haskell 2 though. -- Mark
