Very interesting. This reminds me of reflection in Java. Something
difficult and dangerous to use, so you never use it directly. Instead
you ask a framework or a library ( ~= "upvar" ) to use reflection for
you. Unlike your code, such a framework has been developed and
approved by wizards and tested by millions of users.

The analogy unfortunately stops here: you cannot use reflection
by accident, whereas in shell it looks easy to accidentally stumble
on dynamic scoping.
