Should it still be called, an error is raised. I skimmed past that section, and didn't realise its significance, thinking it was just covering off edge cases of the implementation. I think the core principle behind the various restrictions needs to be made much clearer in the summary of the proposal, because up to that point all the examples just look identical to normal closures with automatic capture by reference. For similar reasons, perhaps a different keyword would be better, so that users don't have a wrong expectation of what it means. Regards, Rowan Tommins [IMSoP]
