antlr - Antlr Cpp templated visitor class

Question

Is there any possibility of templated visitors in AntlrCpp similar to Java implementation? I've a BaseExpression class that I want to return from my visitors but for the sub-rules, I'd like to return ScalarExpression/VectorExpression that derive from BaseExpression. Now, I've to check the type of Any everytime I need to do something specific related to scalar or vector rules. Having a template would eliminate the need for Any and we can directly access the right type of object returned from each visitor method.
