There hasn't been much that would actually affect parsers usage of it. But, when adding new node types, these usually appear in the `Parser::Meta::NODE_TYPES`. `itblock` was added, gets emitted by prism, and then `rubocop-ast` blindly delegates to `on_itblock`. These methods are dynamically created through `NODE_TYPES`, which means that it will error if it doesn't contain `itblock`. This is unfortunate because in `rubocop-ast` these methods are eagerly defined but the prism translator is lazily loaded on demand. The simplest solution is to add them on the `parser` side (even if they are not emitted directly), and require that a version that contains those be used. In summary when adding a new node type: * Add it to `Parser::Meta::PRISM_TRANSLATION_PARSER_NODE_TYPES` (gets included in `NODE_TYPES`) * Bump the minimum `parser` version used by `prism` to a version that contains the above change * Actually emit that node type in `prism` https://github.com/ruby/prism/commit/d73783d065
