“The Python program sleeps for five minutes, the Java program sleeps for 0.3 seconds, and the Haskell program sleeps for 0.3 milliseconds.”
The same sleep(300) means three different durations in three languages, and the code gives no hint. Name it timeout_seconds and the bug can’t hide. This costs nothing but a few characters. NASA lost the Mars Climate Orbiter to a units mix-up, and your codebase is making the same bet one variable at a time.
