Learning Functional Programming in Go

Another time of reflection

Are we frustrated yet? We learned how to code in a concise, declarative functional programming style only to learn that it would probably run too slow to be viable in production. We tried various techniques to speed it up, but nothing we've done thus far with pure functional programming can match the performance of old-school imperative programming.

Our goal is to find a way to program using the declarative functional programming style in Go with performance numbers that meet or exceed expectations.
