Golang Playspace

Playspace for golang experiments, code snippets and personal scrappy tooling. Each idea can:

1. Turn into bigger projects that started off as a single main.go file in a directory under cmd and keep expanding until this code structure makes navigation and usage difficult. Then, the code is moved to a dedicated repository.
2. Stick around as a reference to be used in other projects.
