Re: [Haskell-cafe] bug in ghci ?

Hi titto, You should try to give a complete list of steps which can be run to reproduce your problem. This also includes ghci --version output and maybe some info about the OS you're working on. So how you you load the code into ghci? Using ghci File.hs or :l ? In any case you want to declare the show method: -- yes, I know I should just use 'deriving (Show)' because most -- developers expect Read Show instances to work the common way -- which means they serialize and unserialize data types in a reliable -- way ... instance Show Test where show (Test s) = "my show implementation of Test: Test " ++ s Marc Weber
