While developing an app, I just ran into this scenario:

    class GetCacheRequirements(): PagedGetCacheRequirements(PAGE_SIZE) {

	    var pageNumber = 1

        override var tag: GetCacheRequirementsTag = "Get friends. Page number: $pageNumber"
    }

Problem is, when the repository changes it's requirements, the tag does not change. In this scenario, the tag gets set when the class is constructed which means that it will always has pageNumber == 1. But if I decide to do this:

this.requirements = GetCacheRequirements().apply { this.pageNumber = 2 }

This will result in the incorrect tag.

So, time to think about improving the tag here. Make sure the tag is generated dynamically each time it's needed. So, maybe make it a function? Add something to the docs?
