Yes. It's good to explicitly say that we're talking about changing a symbol's value here, and not just changing a symbol. The notion of "changing" a symbol can mean different things to different readers. Consider (put nil 'toto 42) or (put :foo 'toto 42). Did we change the symbol nil or :foo, both of which are self-evaluating? For some meaning of "change", we did - we changed its property list. The message should be just that you can't change the `symbol-value' of a self-evaluating symbol/variable.
