Well, to the scripter and especially to the user, it appears that the variable a is being changed (mutable means changeable) from "A" to "AB".
And you wonder why Doug can't make heads or tails of this stuff.
We're talking replaced versus changed in this case. They look very similar.
Should I tell the story about Warren complaining about the subtle differences between set and copy while implementing them again? Oh wait, I just did.
