Operator shouldn't compile without proper formal parameters list

Example code:

class Test {
    operator => return 123; }
}

int main() {
    Test t = new Test();
    print(t[4]);
}

According to the spec it is a compile-time error if the number of formal parameters of a user-declared operator with name [] is not 1.

Actual results:
NoSuchMethodException is raised at run time

Expected results:
compile-time error

Please change format to formal in issue's title. Btw is there any way to edit it?

I'm unable to reproduce the issue with the following test code:
class Test {
    operator => 123;
}

int main() {
    Test t = new Test();
    print(t[4]);
}

The following error code is reported no code is executed:

.../dart.dart:2: SyntaxError: Illegal number of arguments
     1: class Test {
     2: operator => 123;

Added Invalid label.

Hmm I got (Revision: 370):

./xcodebuild/Debug_ia32/dart t.dart
An unhandled exception has been thrown

I can't reproduce this problem against https://dart.googlecode.com/svn/branches/bleeding_edge/dart/runtime @­ r771 for dartc or the VM.

The path ./xcodebuild/Debug_ia32/dart looks like a path to the VM executable and not dartc.
