…n slot This PR changes the Hoare-triple notation so `;` introduces the exceptional postcondition as a single `EPred` term rather than a list of exception cases wrapped in `epost⟨…⟩`. This lets the notation express an `epost` variable or any `EPred`, and makes `epost⟨…⟩` an ordinary explicit constructor written in that slot.
