However, some languages (mostly strictly functional) don't enable that sort of "damaging" reassignment, as it would imply improvements of non-regional point out. The reason will be to enforce referential transparency, i.e. capabilities that do not depend upon the point out of some variable(s), but develop the exact same outcomes for the given set of parametric inputs at any place in time.
