When I have many things that share a base class, and I want to be able to reference them both as individual named items, and then do “generic” things to them, it would be quite helpful to be able to pass reference-to-variable to a Blueprint function.
For example, “create UI widget instance of class C, assign it to a member variable, attach it to the view” is a very common thing to do, but I can’t really turn that into a function or macro, because I can’t pass in “the member variable name to assign the created object to” as an argument. Reference-to-variable as a type would solve this.
