I assume you use '-' '>' instead of '->' because it's easier than introducing a
new token?

Using the old formal-parameter list, so a single identifier is a name, not a
type, right?

Right.

I wanted to see how hard it would be to change the parser. Resolving it the
right way shouldn't be too hard, once the parser has constructed the nodes.
