Will need modifying (switch isn't a continue target), but this'll be fine for
now.

Good point. I'll probably need your help figuring this out.

+    node.cases.accept(this);
+    statementScope.exitLoop();
+  }
+
+  visitSwitchCase(SwitchCase node) {
+    // TODO(ahe): What about the label?

We will probably have to make two passed over the switch, one (in
visitSwitchStatement) to gather labels and set up the statement scope, and one
to resolve the labels of continues in the case statements.

I was thinking about something similar.

+    node.expression.accept(this);
+    node.statements.accept(this);
+  }
+
+  visitDefaultCase(DefaultCase node) {
+    // TODO(ahe): What about the label?
+    node.statements.accept(this);
   }
 
   visitTryStatement(TryStatement node) {
