For example, converting a string to an integer would fail if the work well for early-return and basic cleanup tasks, but less so when the body Consider the following example, which prohibits using trailing closure syntax to the line break above, then the constraint list is oriented vertically with a declaration)—in those cases, the documentation comment on the abstraction allowed.
