The Expression Problem, populated by Philip Wadler,  is a often used to standard problem to evaluate programming languages.I think it is a very clear and popular example and I wonder if there are any similar standard problems that are possibly also as widely used and as clear.So, are there any similar standard problems?(In the case of Feature Oriented Programming (link link) I found some standard problems, like:- implementation of a stack with different features- implementation of linked lists- implementation of a calculator- the graph product line- stock broker and bank account examples- hierarchical display)
