Hello,

Is there a description anywhere of the differences between the two, and what would be involved in moving one's application from mtl to monadLib?
No, but such a document would be quite useful and I should probably try to write one, but that might take me a while as I am quite busy at the moment. The good news is that the intreface to 'monadLib' is all in a single place (the module 'Monad.Prelude'), so it is easy to see most of the differences. The web-page (www.csee.ogi.edu/~diatchki/monadLib) also contains a table that lists all the transformers and what operations they support, which would probably be informative to someone familiar with 'mtl'. Also 'monadLib' is very small and has documentation (and examples), so looking through it source code is not unreasonable. -Iavor
