Just finished an epic #fsharp coding binge this week. It was like plugging my brain directly into the machine. There was almost no impedance mismatch between forming a design intention and expressing it in code. I have never felt so productive. The project is an internal tool that I can't talk too much about. Basically it's a console app that pulls data from different teams/departments and "joins" it together (normalizing disparate domain terminology) to produce various reports that it can dump to the screen or Excel.

Wow, these results are sobering. In an effort to turn them around, I’m going to attempt a Twitter #monadtutorial. I realize this has probably been done before, but here goes anyway... 1/

This will not be Haskell-focused. Haskell was my first introduction to monads back in 1999, and it just confused the heck out of me. Instead I’ll use examples from #csharp and #fsharp, since they’re what I know best. 2/
