+#   should be the absolute priority, there may be things like Ruby gems, Python packages,
+#   Rust crates which we may need especially on anything other than an Arch machine.
+# Define a function that runs all updates.
+# This does not care about isolated venv/bundle/whatnot directories, it maintains
+#   the installations in the standard user home folders explicitly.
+# DANGER: this may lead to breaking changes in one language while the others still perform
+#   fine.
