[Haskell-cafe] how to print out intermediate results in a recursive function?

[Ozgur Akgun]

Hi,

There is also this nice trick to use Debug.Trace:

merge xs ys | trace (show (xs,ys)) False = undefined -- add this as the
first case to merge
mergesort xs | trace (show xs) False = undefined -- and this as the first
case to mergesort

HTH,
