TLDR: Go is a great scripting language if you require more than a shell
language.

I recently had to write a Dockerfile generator for caching automatic testing
runs and incrementally caching the build without an actual incremental build in
CICD.

Previously this generator was written in bash and powershell.

Required features for the choosen language were:

- easy xml/general file parsing without external packages
- not slow
- fast startup
- can be easily run with minimal effort

The following languages/runtimes were in the running for this task:

- Deno (TypeScript/JavaScript runtime)
- Go
- Lua
- Nushell
- Python

Deno, Lua and Python require external packages for parsing xml files. Deno
would be easier, because external dependencies can simply be imported with just
an URL. Nushell has problems parsing certain xml files. Go on the other hand
has xml parsing builtin.

Go is also simple to run with `go run main.go`, doesn't require auxillary files
(like `packages.json` with npm), but can also be compiled and cached. Also, Go
is trivally multi-threaded, which is a big problem in many interpreted
languages.
