 // Dart test program for testing named parameters.
 // Specifying named argument for not existing named parameter is run time error.
 
 // This test is very similar to NamedParameters3Test, but exersizes a
 // different corner case in the frog compiler. frog wasn't detecting unused
 // named arguments when no other arguments were expected. So, this test
 // purposely passes the exact number of positional parameters
