I’d like to refer to an instance of a stan_model (i.e., an instance of a class which is defined in the stanc generated file) without having the specific class known at compile time. The parent class of is stan::model::prob_grad, so I thought I could use that, but I’m hitting problems using a pointer…

Thanks. This makes sense. By “refer to” I just mean use a pointer to prob_grad instead of a pointer to the specific model. I can see that C++ doesn’t support what I’m trying to do: figure out the type/class of the specific stan model at runtime. It would be very cool indeed if it did. I wonder …

Is there a proper base class for stan_model?

We’re starting to design one. See Prelim proposal for model base class.
