Howdy. All errors should actually go thru:
public void emitErrorMessage(String msg) {
System.err.println(msg);
}
The
System.err.println("BR.recoverFromMismatchedToken");
you see is a debugging print. Ooops. Actually, it's gone in my main
line of code. so we're cool.
Are there others? That's the only one I see.
