The easy branches could generate expressions (which were basically AST Nodes), the more involved branches would recursively call into the same function, until eventually you had an expression generated.

The new parser has functions to match the states of parsing in the spec. For example https://tc39.es/ecma262/#prod-VariableDeclaration has a matching function `read_variable_declaration`. This not only makes it better to maintain but easier for new contributors to get involed, as following the parsing logic of the spec is easier than before.

This works because the tokens live just as long as the parser operations do, so we don't need to copy the tokens.\
