What 's the best equivalent haskell approach ? thanks in advance, Pieter

The preferred approach is to look at your code, figure out where you are using tail (or could be calling something that uses tail) and use the "trace" function to output logging info.

A nice way to automate that is using LocH from Hackage. The original announcement: http://www.haskell.org/pipermail/haskell/2006-November/018729.html
