[Haskell-beginners] Logging in Haskell

    Hi community,

As my Haskell programs grow above 100 lines of code, I feel the  
necessity to trace the execution of them more closely. In imperative  
languages one may use logging facilities for checking intermediary  
values of variables, the execution flow, etc. How this usually handled  
in Haskell (I bet that despite the fact that in Haskell it is  
relatively easier to write bug-free and checked code, the industrial  
systems still need some logging being done)?
