"That said, the BGGA proposal is a bit of a disaster in my opinion: the distinction between "restricted" and "unrestricted" closures, along with non-local returns, just makes no sense." The BGGA proposal was recently updated: "The concepts of restricted and unrestricted function types and closures have been removed. Now, all lambda expressions are restricted. The equivalent of the previous specification's unrestricted closure may be passed to a method by using the control invocation syntax." It is rumored that it is something like a compromise between the BGGA and the FCM proposals that Sun is pushing.
