+# Note: Recent `tree-sitter-cli` requires libc6>=2.39, while
+#       this image is based on 2.36, see https://hub.docker.com/_/haskell/.
+#       v0.24.7 seems to be the newest version supporting libc6-2.36.
+#       And we rely on some recent features of `tree-sitter-cli` (like `--cst` and
+#       parsing from stdin), that is why we build from source.
+#
+#       If a newer `haskell` image with higher `libc6` version is published
+#       in the future, this may be replaced by directly downloading the pre-built
+#       binary like the commented following snippet (and remove the `rust` builder).
