I (the author) familiar with functional languages, have implemented a compiler for a small one and such. However, for every day applications that are non-algorithmic attempts to express them using functional constructs have often been a strain. I've been watching projects go late due to this. There are many things, however, that I find much clearer to express in terms of functional programming constructs. But nominal business apps which show a GUI and CRUD from one location to the next or do a fairly simple data transform with a bit of boolean logic? Not so much.

The formatting is a result of the copy-editing process. The code excerpts were all from the beginner tutorials linked from the sites or wikipedia.
