Comment(by simonpj): Well, at the moment a `rec {...}` block can't be the last statement in a `do`. But after talking to Simon I realise that we could change that, by adopting the following translation: {{{ do { ...; rec { ...; e } } ==> do { ...; rec { ...; res <- e }; return res } }}} Now if the initial "..." was empty we could write {{{ do rec {...} }}} as "guest" (Jack, perhaps) wants.
