Assignments ordinarily let a variable to hold unique values at unique instances during its life-span and scope. Even so, some languages (largely strictly functional) never make it possible for that kind of "destructive" reassignment, as it would imply modifications of non-neighborhood state. The function should be to enforce referential transparency, i.e. features that don't depend upon the point out of some variable(s), but generate precisely the same effects for any presented set of parametric inputs at any place in time.
