As I said, I don't want to use such a solution because I need this feature
for specific use case and it just feels wrong to have to setup such
solution just to know the real type.
I'll go with the type_id solution, as I thought. I just hope I will not get
in a case where I need to use the lib in a context that doesn't allow RTTI.
But I guess it's more rare today.
