I was able to get through YAHT this evening. Most of it was review from the other material I’ve worked through.

At this point, I would say I’ve learnt haskell. I know the syntax. I’m comfortable with the tools and standard libraries. Monads are still iffy. Not the using part but more the building brand new ones part. According to YAHT, that is “super haskell guru” territory.

At this point, I should go forth and produce haskell code. That is the one true way to master a language.
