in thread ref to read-only alias ... why?

The literal «123» should return a modifiable value.

Could you elaborate on that please? I don't find that neither convincing nor intuitive. If that's true, why error message "Modification of a read-only value" exists at all? By the same logic 123++ should be working fine, no?
