# Smoke test: pins the walkthrough's documented "Trying it" transcript.
# Regression guard — the example's code (copied straight into
# content/walkthrough/en/toy-calc.md's fenced block) was never actually
# build-tested before and had a real compile bug (missing <optional>,
# unqualified ParseError) that went unnoticed for a while.
