This looks good--it does what is exactly done for superClass in the parser. Thank you for fixing this.

I'm getting one failing test with the message

Running org.antlr.v4.test.runtime.csharp.TestLeftRecursion

Too long with no output (exceeded 10m0s): context deadline exceeded

I don't think that test is actually running my changes (I'd expect runtime.csharp is using the c# runtime, not parsing c# using go). I'm going to rebase on the development branch and retry the tests.
