You have it wrong. Only the most basic code on Earth has unwrap in it. Real-world code will either actually handle the error with `match`, forward it with `?`, or unwrap it with `except` iff it's sure that an error will not occur.
522 results in servo. Granted, some (but not all) are in tests.
`.unwrap()` is expected to be in every code base out there, as there is rarely much point in handling errors such as tainted mutex locks.
