+ * This is pretty clever: When adding the ConditionMatcherVisitor as first visitor, it
+ * sets the condition verdict of a ConditionInterface node in visitBeforeChildren().
+ * Adding the AstBuilderVisitor as second visitor, the AstBuilderVisitor will not be
+ * called for ConditionInterface children that did not evaluate to true.
+ * This way, we can both evaluate conditions and build the AST in only one traversing round.
