The original RBS rewriter runs after the parser has assigned unique names to anonymous parameters, which it can then pull out of the method definition. With the Prism RBS rewriter, we can't generate unique names until later on when the translator is run. We can use static names instead as `*`, `**`, and `&` are guaranteed to be unique anyway (in fact this is already the case for the block param).
