This sounds like how I am currently programming, but I consider myself an FP novice. In Python, I avoid writing classes until I need a data structure too complex for a dictionary of tuples. In C# I have to have more classes, but I am still aiming towards a more functional style by preferring passing parameters and returning values over manipulating instance variables. I would like to learn F# and start using it for my .net work, but I haven't had the time yet.
