I am writing a simulation function that loops over simulating a data set and fitting multiple statistical models to the data. The exact form of the output will depend on which characteristics of the fitted models I wish to preserve. My inclination is to pass a callback function to take the set of models after each iteration and extract and save the characteristics of interest.
However, I have a vague recollection that passing a function as an argument to another function was discouraged. I believe it made type inference awkward. Was that ever the case and, if so, is still the case?
