An interesting view.

Apparently, you identify "binding" and "scope" (or more precisely its shape).
And in this view, the binding is changed by language construct introducing
"variables".

My view is a bit different. I identify "binding" with the map
from variables to values, i.e. the environment in which expressions
are evaluated. This is more the "scope's content".

I am not sure which view is more correct.
