I had fun playing through all the challenges. But I don't think I walked away with a better idea of functional programming. This is closer to "learn LINQ", seeing as we're only chaining functions. I would be interested in seeing this expanded to include passing functions to functions (that is, make the user build a tree of functions, not a list). And yes, that might put you into hot water regarding how to communicate signatures and such.
