// a rule like: x -> 'a' | 'b' | 'c'; would expect to have an @choice rule and a single unnamedToken() rule
// Because the options all only have a single token the code will generate a getter for the "" named tree node
// However, this will fail because in this case the ast not would look like [@choice: 0, RULE_NAME: 'a']
// instead of simply ["": 'a'] which is what would be expected.
// To solve this problem the second if block is added to catch this.
// A better solution would be to do `ast.First(ast.First(c.Node, "TheRule").Node, "") but the codegen loses
// the rule name, this solution is Good Enough(TM)
