I can imagine
return? tree_node.left
return? tree_node.right
although my real code would probably be more like
if tree_node.left is not None:
return "left", tree_node.left
if tree_node.right is not None:
return "right", tree_node.right
where adding the "left" and "right" markers makes the return? feature
impossible to use.
The proposed feature reminds me of the `zod` function (was that the actual
name?) that returned 0 rather than bringing on a ZeroDivideError. It would
cement a strange corner-case into the language.
