docs: =============================================================== Parsing function Returns an array of nodes created by parsing the given rule repeatedly until it fails or the end of the input is arrived. One Astnode is created for each time the token is parsed successfully, whether or not it explicitly has the "_createAstNode" flag set explicitly.
