Louis Gesbert 1efda5ca22 Typing defaults: support nested priorities ... The way nested priorities are encoded use `< < excs | true :- nested > :- x >`, which imply that `nested` can actually be ∅ ; to cope with this, the typing of default terms is made more generic (the return type is now the same as the `cons` type `'a`, rather than `<'a>`). For the general case, we add an explicit `EPureDefault` node which just encapsulates its argument (a `return`, in monad terminology).		2023-11-27 11:09:08 +01:00
