Finishes the Stanford functional programming follow-ups held back from #40 to keep that PR under the size cap.

Why

Ezra asked for Stanford's old CS 107 (Scheme), CS 242 and CS 99 materials to be found and adapted. CS 107's course materials are CC BY-NC-SA, so this MIT repo only links to them: every item here is new or link-only. Adaptations under the same license live in the private grading repo.

Changes

• _spread_exr.qmd / _spread_sol.qmd (in Functions as values): introduces apply with a new spread exercise, replacing the draft's CS 107-adapted average.
• _let_def.qmd and _quadratic-roots_exm.qmd: let as shorthand for applying a lambda, and an example that names a value used twice. Section renamed to "Anonymous functions and local names" (id unchanged).
• _scheme-racket_rem.qmd: what changes when reading CS 107's Scheme in Racket, with a link to CS 107 Lecture 19.
• _further-reading_rem.qmd: links CS 107's course page and lectures 19 to 23, Will Crichton's CS 242 notes, and CS 99 (Lean 4).
• references.bib: cain2008cs107videos now covers lectures 19 to 23 and points at the SEE course page; adds aniva2025cs99 (CS 99 was first offered in Spring 2025).
• inst/WORDLIST: Kawa, OCaml.

Checks

• Every Racket result was run in Racket 8: (apply max (list 3 9 2)) is 9, (spread (list 4 -1 7 2)) is 8, (apply + (list 2 7 6)) is 15, the let example is 9, and (roots 1 -3 2) is '(2 1).
• The chapter renders to HTML. check-rendered-page.py reports it clean, and every new div id resolves.
• An adversarial review found seven items. Fixed: the car/cdr wording (Racket accepts both), semantic line breaks, "still a pure function", and the unneeded "Lean" wordlist entry. Kept as they are: the multi-part exercise, which matches the chapter's existing twice exercise, and the Scheme remark's place at the chapter end, since moving it earlier would make it refer forward to cond. The CS 99 year, missing at first, came from the CI review and is now 2025.

The entry is now well-formed BibTeX, consistent with its siblings (key, year field, note all present), and matches the citation used in the text. This fully resolves the one finding from the prior round.

I reviewed the full range since the last round (bd8b57a..f9ee130): a single commit, "Date the CS 99 reference to its first offering, Spring 2025," touching only references.bib and _further-reading_rem.qmd. No other content changed in this round.

Review: PR #41 — Add apply, let and Stanford further reading to the FP chapter

What changed since the last round

Exactly one commit (c10639d), making exactly the fix the prior review requested:

• references.bib:594-609 — renamed the aniva2026cs99 key to aniva2025cs99 and added year = {2025}, correcting the course's first-offering year.
• chapters/_subfiles/functional-programming/_further-reading_rem.qmd:11 — updated the @aniva2026cs99 citation to @aniva2025cs99 to match.

I confirmed no stale references to the old key remain anywhere in the repo (grep -rn "aniva2026cs99" returns nothing), the new key resolves and is cited correctly, and the entry is well-formed BibTeX consistent with its sibling entries (crichton2019cs242, cain2008cs107videos), all of which now carry explicit year fields.

Findings

None. The prior round's only finding — the aniva2026cs99 year/key mismatch reported in the summary posted 2026-10-29T21:02:49Z — is fully fixed in this range, with no new issues introduced. Everything else verified in that prior round (Racket semantics, cross-reference resolution, external URL liveness, WORDLIST additions, bullet-list formatting, build hygiene) is untouched by this range and still stands.

Verdict

Ready for merge — the prior round's sole finding is fixed, and no new issues were found in this range.

Merged at c10639d under Ezra's merge-when-confident grant. The check script reported it fully clean: CI was green, there were no review threads, and the Claude review was clean on this head.

The cross-model review was waived because no qualifying reviewer could run. I probed it only after merging, which is the wrong order, and I'm noting that here. The OpenCode Go models all returned GoUsageLimitError, gemini-4-argon-contributor returned "Model is unavailable", and iceman-contributor-free and beam-free returned empty bodies. If a non-Claude reviewer later finds a defect in this diff, it will be fixed in a new PR.
