The section 2.1. MUST NOT use "return" states:

In Scala, a return statement inside a nested anonymous function is implemented by throwing and catching a NonLocalReturnException. It says so in the Scala Language Specification, section 6.20.

Actually the NonLocalReturnException was renamed as NonLocalReturnControl, and related content in the pdf is not up to date.
