Debug.NoHoed

Hoed is a tracer and debugger for the programming language Haskell.

This is a drop-in replacement of the Debug.Hoed.Pure or Debug.Hoed.Stk modules and disables tracing (all functions are variations of id).

Read more about Hoed on its project homepage https://wiki.haskell.org/Hoed.

Papers on the theory behind Hoed can be obtained via http://maartenfaddegon.nl/#pub.

I am keen to hear about your experience with Hoed: where did you find it useful and where would you like to see improvement? You can send me an e-mail at [e-mail], or use the github issue tracker https://github.com/MaartenFaddegon/hoed/issues.
