Relvars are essentially a programming device for mimicking assignment, although it's no stretch to imagine a methodology using their names for some purpose, eg., place-holders. As far as I know, they might not always be needed depending on the programming language, say a functional one, I have little experience with those even though I think some of their motives are promising.
