Re: [Haskell-cafe] out-commented code vs. case with redundant pattern matches
Henning, how about putting the branches into their own variables. Admittedly this pollutes the namespace but is much more readable IMHO. workflow = new_workflow where new_workflow = putStrLn "A" old_workflow = putStrLn "B" I suppose GHC complains neither about unused where clauses nor about unused top-level bindings. At least with GHCi 7.8.3 the above code produces no warnings. Olaf

It complains with -Wall, which is a good thing. But in this case I can suppress the warning individually by prepending an underscore.
