On using small classes with Python match-case statements

	19:49 < dcb> so, I'm looking for opinions on a pattern I often end up using with python that I borrowed from erlang and haskell. The gist is to wrap some object inside a
	small class just so I can use it in a match-case statement. Here's a snippet should give you an idea: https://bpa.st/C6LQ
	19:50 < dcb> others often react in one of two ways: (╭ರ_•́) or ¯\_(ツ)_/¯
	20:00 < phy1729> IMO Python's typing isn't algebraic enough for that to feel natural. Though TIL __match_args__ so maybe that'll change in my head.
	20:03 < phy1729> dcb: though I'd be inclined to make Field generic https://mypy-play.net/?mypy=latest&python=3.12&gist=b4aa6967a03c0ac147130af73f8942db
	20:17 < dcb> XenophonF: these patterns often end up appearing when I'm debugging branching logic early on development. Good call for making the base generic. And
	`__match_args__` is something I've started to use quite a bit recently

Docker Compose configuration for setting up a PostgreSQL container with a health check

	# Docker Compose configuration for setting up a PostgreSQL container with a health check
	#
	# This configuration pulls the latest PostgreSQL image and sets up a health check
	# to monitor if the PostgreSQL service is ready to accept connections. The health check
	# uses the 'pg_isready' command to check database readiness.
	#
	# Environment variables are used to configure PostgreSQL credentials and database settings.

An unfinished idea I had to generate documentation for tagged releases and extant feature branches

	# This was inspired by https://www.codingwiththomas.com/blog/my-sphinx-best-practice-for-a-multiversion-documentation-in-different-languages.
	# However, I'm taking a different approach.

	# Generate documentation for tagged releases and extant feature
	# branches. Take care to handle remote branches, too, not just local
	# branches or local remote-tracking branches. However, do not alter
	# the working directory in any way.
	docs: $(LOCALES) \| $(PYPACKAGE_NAME).egg-info
	# Create missing remote-tracking branches.

Use this ONE SECRET HACK to map GitHub Actions secrets/variables to OpenTofu input variables LIKE A PRO (site reliability engineers HATE THIS!)

TL;DR—Continue using lowercase OpenTofu input variable names, but prefix the corresponding GitHub Actions secret/variable names with an underscore. Then add the following step to your continuous delivery workflow:

      - uses: easyware-io/export-to-env@v1
        with:
          secrets: ${{ toJSON(secrets) }}
          vars: ${{ toJSON(vars) }}
          only: ^_.*
          prefix: TF_VAR
 transform: lowercase
