Thanks for that! It was a nice introduction, I have a colleague who usually made my eyes glaze over when he started about FP, but now that I have seen it in an environment that I understand and use in my day to day job, a lot of "a-ha" moments occurred in rapid succession. I also liked the humorous bits. It's all pretty self-explanatory and well put, a little Googling will fill in any gaps an interested pupil might face.
