New shell scripting language, a new tablet, and in-product messaging
If you're only occasionally writing shell scripts, Amber may not be a priority for you. In such cases, linting tools like ShellCheck could be more beneficial. However, if you find yourself frequently writing shell scripts, to the point where you're considering Python or Ruby for better re-usability, then Amber is definitely worth your attention.

Amber – the programming language compiled to Bash
As carlinigraphy points out, shellcheck [0] exists, and can easily be put into pre-commits, a CI pipeline, etc. This would have almost certainly flagged your problem immediately.
> I would be willing to learn a sane language, but bash isn't one.
It's a general language that has to be both an interactive interpreter and script executor, and it needs to support a huge variety of architectures and kernel versions, as well as historical decisions. It's going to have some cruft.

How I use Devbox in my Elm projects
These projects use Caddy as my local development server, Dart Sass for converting my Sass files to CSS, elm, elm-format, elm-optimize-level-2, elm-review, elm-test (only in Calculator), ShellCheck to find bugs in my shell scripts, and Terser to mangle and compress JavaScript code.

Ask HN: Is there a GUI for bash shell?
ncurse, dialog, zenity[2]. i/o buffering may be an issue [3a,3b]
Assuming using same account, use history command to show past commands[0a, 0b]
'load random example' on shellcheck using own custom examples from history command.[1]

Google ZX – A tool for writing better scripts
If I want to write better shell scripts I usually run shellcheck and adjust accordingly or if I need facilities not provided by the shell i switch to a full fledged programming language. Ans oh yes, `sh` is present almost on every BSD and Linux box for free so I consider it an important thing to at least be comfortable with.

How I use Nix in my Elm projects
When I run nix-shell at the root of the project it puts me in a Nix shell that contains, among other programs, caddy and shellcheck. Notice that in the shellHook I add the project's shell scripts to the PATH. So once I'm in the Nix shell I can, among other things:

Regex support to list modules in .cabal?
I have also seen some projects on github like ShellCheck which first make a library, expose all the modules and then simple add that do build-depends of the final executable. Is this the recommended approach than having just one executable and adding all the modules to other-modules:?

Try Clojure
Check out Babashka. It's a single binary that runs Clojure without a JVM. It also starts up really fast and uses a lot less memory: https://github.com/babashka/babashka
That said, there are reasons you may want to use the JVM Clojure later. It might be interesting to read the replies to another poster with similar concerns about the JVM: https://news.ycombinator.com/item?id=40445415

What's the value proposition of meta circular interpreters?
I've tried researching this myself and can't find too much. There's this project metaes which is an mci for JS, and there's the SCI module of the Clojure babashka project, but that's about it. I also saw Triska's video on mci but it was pretty theoretical.

Critique of Lazy Sequences in Clojure
Clojure's lazy sequences by default are wonderful ergonomically, but it provides many ways to use strict evaluation if you want to. They aren't really a hassle either. I've been doing Clojure for the last few years and have a few grievances, but overall it's the most coherent, well thought out language I've used and I can't recommend it enough.
There is the issue of startup time with the JVM, but you can also do AOT compilation now so that really isn't a problem. Here are some other cool projects to look at if you're interested:
