$ cat foo.dart
class Fisk {
  call() {}
}

main() {
  new Fisk().params;
}
$ ./sdk/bin/dart foo.dart
Unhandled exception:
Closure call with mismatched arguments: function 'params'

...

I would have expected a message more like:

Class 'Fisk' has no instance getter 'params'.

The current error message was introduced in r22209.
