Yes, e.g. in Marpa::R2 test suite — https://github.com/jeffreykegler/Marpa--R2/blob/master/cpan/t/sl_json_ast.t
parse() <https://github.com/jeffreykegler/Marpa--R2/blob/master/cpan/t/sl_json_ast.t#L289> -- produces an abstract syntax tree (ast) of JSON test, decode() <https://github.com/jeffreykegler/Marpa--R2/blob/master/cpan/t/sl_json_ast.t#L301> traverses it to produce a data structure. Another example <https://github.com/jeffreykegler/Marpa--R2/blob/master/cpan/t/sl_timeflies.t>: ast is produced by calling value() <https://github.com/jeffreykegler/Marpa--R2/blob/master/cpan/t/sl_timeflies.t#L137> on recognizer, bracket() <https://github.com/jeffreykegler/Marpa--R2/blob/master/cpan/t/sl_timeflies.t#L143> walks the tree. There is also a gist from the author — https://gist.github.com/jeffreykegler/4747725 Hope this helps, rns.
