Reviewer's GuideThis PR refactors and enriches the Haskell parser analysis documentation with reflowed text, new sections (control-flow, expression grammar, utilities), expanded Rust porting guidance and error-handling notes, and corrects Makefile indentation by replacing spaces with tabs so that make targets run properly.

Hey @leynos - I've reviewed your changes - here's some feedback:
- The new control‐flow and expression grammar sections are very detailed—consider breaking them into smaller subheadings or separate files (or using collapsible sections) to make the doc easier to navigate.
- Since the porting notes must stay in sync with the Haskell parser, you might automate extraction of grammar rules or code snippets from Parse.hs to reduce manual drift.

249-255: Still uses manualmapfor tab stripping – previous optimisation not applied.let s' = map (\c -> if c == '\t' then ' ' else c ) sReplacing this with
Data.Text.replace "\t" " "(or similar) is clearer and avoids an explicit per-character lambda.Same point raised in the earlier review; consider updating if you touch this snippet again.

21-23: Good uptake of the previous nit –filteron$*is clearer than string-searching$(@).The rule now only triggers the

🧹 Nitpick (assertive)
tools target exits silently—emit a friendly diagnostic on failure.
If any of the commands are missing, command -v just returns a non-zero status; with the leading @ Make prints nothing, leaving users puzzled. A short message makes the failure self-explanatory.
-tools:
- @command -v mdformat-all >/dev/null
- @command -v $(CARGO) >/dev/null
- @command -v rustfmt >/dev/null
+tools:
+ @command -v mdformat-all >/dev/null || { echo "✖ mdformat-all not found"; exit 1; }
+ @command -v $(CARGO) >/dev/null || { echo "✖ cargo not found"; exit 1; }
+ @command -v rustfmt >/dev/null || { echo "✖ rustfmt not found"; exit 1; }Optional, but greatly improves usability.
🤖 Prompt for AI Agents
In the Makefile around lines 26 to 31, the tools target uses silent command
checks with '@command -v', which hides failure messages when commands are
missing. Modify each command check to emit a clear, friendly diagnostic message
if the command is not found, by removing the '@' and adding conditional echo
statements or using a shell conditional to print an explanatory error message
before exiting with a non-zero status.
