Some languages use mathematical symbols to name functions that are derived from mathematical rules/principles (e.g. the Scalaz library). I think it's a good idea. If you're implementing function composition, just use the mathematical symbol for composition, don't pull a new name out of a hat. A lot of people complain about it, the main reasons being: - it's annoying to type - a lot of developers actually don't have a math background and have no idea what the symbols mean
