I just tried to use the default case in a visit, but get a "java.lang.UnsupportedOperationException". The code below all results in the error.

visit({}) {case {3} : println("a"); default : println("b"); }

visit({}) {default : println("b"); } 

visit({}) {default: ; }

According to the tutor, this is correct syntax. What is going wrong here?

The default in a visit is not supported by design, but perhaps that was a mistake? Do you think its useful to have?

I think it might be useful, but in any case the documentation should be updated. Because at the time of my question it said that the default could be used in a visit.
