[Haskell] modern language design, stone age tools

[MR K P SCHUPKE]

>Thank you for the programming practice recomendation,

Sorry if it seemed like that... I was really trying to suggest
practical measures that someone could use in the absence of a
debugger - but I do feel that 'commercial quality' code
should be bullet proof, and of a different calibre to code
for personal use, or academic research.
