We implement a new
doelaborator for extracted monadic code. The new elaborator is only triggered fordoblocks of typeResult, and there is a new optionAeneas.newDoElabwhich can be unset to use the old elaborator.The new elaborator works on a subset of the
dosyntax which doesn't include early returns, so we can avoid any do jumps and the resulting expression will be a sequence of binds.We also treat the pattern matching syntax in
letbindings usingFunction.uncurryto avoid the built-inmatchsyntax elaboration.Included is a new delaborator that delabs the new expressions to the expected syntax.
