You make a comment about precedence. When I wrote that up, it was
basically just "that seems about right"; whether it's equal to lambda,
equal to if/else, above both, below both, or in between, is free to be
tweaked according to what makes sense. Nobody has to date discussed
the exact precedence order, so feel free to tweak it for the benefit
of implementation.
