Let's say you have an untrained puppy which has to release some smelly gifts.

The #Python way would be running after the puppy and picking up the poop, #C would explain the puppy where it should go poop in a first training session but wouldn't check on it which could lead into some piles on your neighbours favourite flowers and #Rust would train the puppy where exactly he should poop and would also make sure that he poops into the right place.
