This is pretty much what I expect from an 'outcome' vocabulary type. In my mental model, a 'none_t' would cover the 'partially formed' nascent and/or forgot-to-produce-an-outcome state which is never looked at besides contract checking. The failure to produce a T (i.e. violation of postcondition) is reflected in error_code or exception_ptr. Ciao Dani -- PGP/GPG: 2CCB 3ECB 0954 5CD3 B0DB 6AA0 BA03 56A1 2C4638C5
