I would like to perform an operation on an argument based on the fact that it might be a map-like object or a sequence-like object. I understand that no strategy is going to be 100% reliable for type-like checking, but I'm looking for a robust solution. Based on this answer, I know how to determine whether something is a sequence and I ...
