I hate this error. Whilst arguably this is an "untested" extension
to Standard Haskell, it seemed pretty sound in practice. Can't
we at least have it back as a GlaExt? (MSExt?) I'm starting to
feel more than a little Quaint having to use ghc-3.01, just to get
my programs to compile... (If anyone has a good systematic workaround
to suggest, I'm all ears.)
ghc-4.00 -c Intervals.hs -H30m -K2M -recomp -fglasgow-exts -cpp -syslib
misc -Rgc-stats -dshow-passes -fmax-simplifier-iterations4
-funfolding-use-threshold-0 -fvia-C
Intervals.hs:460:
Illegal constaint `Ord (s e)' in instance context
(Instance contexts must constrain only type variables)
[etc, etc]
Slainte,
Alex.
