Wrong compliant example in squid:S3398

The rule description contains this in the compliant example of S3398:
Outie.this.increment();

That’s wrong (it’s copy&/paste from the non compliant example). Instead it must be only
increment();
because there is no more such method declaration at the outer class.

Hello Micheal,

Thanks for spotting this small mistake.

The RSPEC-3398 has been modified accordingly.

Best,
Quentin
