[Haskell-beginners] Writing an instance of Read?

[Mike Meyer]

Is there a tutorial - or anything at all, for that matter - on writing
Read instances? Particularly so that it integrates properly types that
incoporate your type and derive Read? Real World Haskell gives one
simple example (which doesn't use the first argument), points out one
problem with the example, then says "many people find it easier to use
Parsec." And that's the best such I could find.

     Thanks,
     <mike
