I did not say that, 
I said it is possible to write a Javascript engine that can.
Would that be forbidden by the ECMA specs?

I don't think so.

All variables in Javascript are in a sense immutable,
but some shorthand operators make it seem they are.

You might say [ I say only apparently so ] 
    i++;
shows mutability.

But [seen the inner workings of string concatenation]
    mystring += " add this to the string";
certainly not.
