# Smoke test: pins the walkthrough's documented "Trying it" transcript.
# Regression guard — this example previously called parse() to "set up
# the cursor" before driving nextRow(), which segfaulted (parse() tears
# the cursor down as soon as its own start() returns); replaced with the
# library's openStream(). This test would have caught that.
