That looks nicer than cf-promises today:

bundle agent main
{
      methods:
        "t" usebundle => t();
}
bundle agent t( param )
{
  defaults:
      "param" string => "DEFAULT VALUE", if_match_regex => "";

      reports: "$(param)";
}

cf-promises -cf ./test.cf 
./test.cf:5:0: error: Conflicting arity in calling bundle t, expected 1 arguments, 0 given
   error: There are syntax errors in policy files
