 Outlining an expr can be used to make a function smaller, e.g. by outlining an unlikely

+A common use case is to `@outline` the code that throws exceptions, since this should be a
 rare case, but it can introduce a lot of complexity to the generated code, which can
 sometimes harm the compiler's ability to optimize.
