Re: [Haskell-cafe] Pattern Matching

(And, entertainingly, because the incorrect version is perfectly valid source code, no compiler errors or warnings...)

If you actually turn on compiler warnings (-Wall), I think you will see something like andrew.hs:10:10: Warning: This binding for `eVENT_QUIT' shadows the existing binding defined at EventLog.hs:43:0 In a case alternative and so forth, for every incorrect alternative. Regards, Malcolm
