⚠️ Note: This is still an experiment.
## Motivation
My main motivation was to try out generics in Go. I jumped straight into the usual suspects: [`Filter`](https://github.com/gtramontina/go-extlib/blob/main/collections/filter.go) and [`Map`](https://github.com/gtramontina/go-extlib/blob/main/collections/map.go). When testing these, I saw the need for assertion functions: another opportunity to exercise some more generics! It is now part of this ext-lib under lives as an [testing/assert](https://github.com/gtramontina/go-extlib/blob/main/testing/assert).
Later I thought it would be nice to implement [`Set`](https://github.com/gtramontina/go-extlib/tree/main/set), and then [`HashMap`](https://github.com/gtramontina/go-extlib/tree/main/hashmap), with which I got carried away and ended up implementing a somewhat naïve [hasher](https://github.com/gtramontina/go-extlib/blob/main/internal/hash/hash.go) (you can read more on the rationale on [this commit](https://github.com/gtramontina/go-extlib/commit/808ac8236c433587c4dc2f85479c1189a5df6010)).
When I realized, I was already having fun with [`Maybe`](https://github.com/gtramontina/go-extlib/tree/main/maybe), [`Either`](https://github.com/gtramontina/go-extlib/tree/main/either) and [`Result`](https://github.com/gtramontina/go-extlib/tree/main/result). Here is where I stumbled upon some limitations of Go generics. Right when I was experimenting with it, I came across a blog post by [@hypirion](https://github.com/hypirion) titled "[Type-Safe HTTP Servers in Go via Generics](https://hypirion.com/musings/type-safe-http-servers-in-go-via-generics)" where the author bumps into these same limitations.
When writing software in Go, I've always wanted slightly higher level constructs, especially to represent business domain concepts. Some may say I haven't fully embraced Go. Perhaps I haven't 🤷. But I sure know people who'd also like to go up in abstraction a tad bit.
Hope this is enough motivation… 😅
⚠️ As the note above says, this is an experiment and no attention was paid to performance or allocations.
