If we need to store something else -- the language forces to create a new box (declare a new variable), we can't reuse the old one.

Though it may seem a little bit odd at the first sight, these languages are quite capable of serious development. More than that, there are areas like parallel computations where this limitation infers certain benefits. Studying of such a language (even if not planning to use it soon) is recommended to broaden the mind.

Being a "constant" just means that the value never changes. But there are constants that are known prior to execution (like a hexadimal value for red), and there are those that are *calculated* in run-time, during the execution, but do not change after the assignment.
