Am I correct?
Yeah you cannot overwrite "x" in the function expression unless you
declare it first
In case a of declaration, you declare a variable, not a FE ;)
And the name of a function is a different property, than a name of a
binding in an environment to which it's bound.
P.S.: per both, ES3 and ES5 a name of a NFE here has {DontDelete +
ReadOnly} attributes (in ES5 -- it's "immutable binding"). So, an
implementation which shows you the function instead of `123` is correct.
