Why would you need to do that, though? What's the practical use case for
this, that you need to do it frequently enough to want a way to do it
without using a temporary?

Or do you think that, as the thing that it short-circuits to the end of,
"same atom_expr unbroken by parentheses" [a concept which, I remind you,
*does not exist* in AST] is somehow simpler or easier to explain than
"same chain of Attribute/Call/Subscript operations"?
