Go Functional Programming

This library is cursed and you probably shouldn't use it. It relies on the Dark Arts to enable a very non-idoimatic way of writing Go.

I was inspired by @fossker's wonderful talk at Doomconf 2022H2 and his Common Lisp Transducers package and documentation.

But this is a different approach that aims to build upon Go's existing standard library to introduce transducers in a simple way alongside a lot of other FP features that I've wanted across various projects.

There are many FP/utility libraries for Go. This one is mine.

The end result is the ability to write Go code that looks like this

Transduce(
	Integers(),
	Chain4(
		Curry2(Take[int], 5),
		Delta,
		Curry2(Map, func(i int) []byte {
			return []byte(strconv.Itoa(i))
		}),
		Visitor(Curry2(Write, io.Writer(&buf))),
	),
	Collect,
)

None of the ideas in this library are new. I'm mostly copying features from the wonderful Clojure and of course Rust.

There are also some other kinda misc things in this library. As its grown it's become more of a general purpose utility library that I use. You can easily import just the parts you want.
