Explore method dispatch to avoid if(class(thing)) do (function) else do (other_function)

[njtierney]

e.g., Use method dispatch inside of calculate to avoid

    if (is.greta_mcmc_list(values)) {
      result <- calculate_greta_mcmc_list(
        target = target,
        values = values,
        nsim = nsim,
        tf_float = tf_float,
        trace_batch_size = trace_batch_size
      )
    } else {
      result <- calculate_list(
        target = target,
        values = values,
        nsim = nsim,
        tf_float = tf_float,
        env = parent.frame()
      )
    }

Thanks @maelle for the suggestion
