Re: [Haskell-cafe] Is there a way to see the equation reduction?

But I am more interested in seeing the expansion and reduction that the execution encounters as it lazily evaluates the function.

Have you tried GHood? http://www.cs.kent.ac.uk/people/staff/cr3/toolbox/haskell/GHood/ It is a bit like the recently-released Vacuum visualiser for data structures, except that it also animates the reduction sequence. (Have a look at some of the online examples - you can view the reduction steps right there in your web browser.) Regards, Malcolm
