Suggest LANGUAGE pragmas instead of -XFoo
Minor, but still: Currently GHC says:
readFail037.hs:4:1:
Too many parameters for class ‛Foo’
(Use -XMultiParamTypeClasses to allow multi-parameter classes)
In the class declaration for ‛Foo’Maybe it is just me, but generally I find LANGUAGE pragmas are the way to go. So I think it should read
readFail037.hs:4:1:
Too many parameters for class ‛Foo’
(Use {-# LANGUAGE MultiParamTypeClasses #-} to allow multi-parameter classes)
In the class declaration for ‛Foo’Note that it is easier to copying MultiParamTypeClasses (by double-clicking), entering "-X", and pasting, than copying XMultiParamTypeClasses and removing the X again.
If noone complains or someone says that it is a good idea I’ll fix it myself.
