The idea is that YOU write "local:", and the interpreter, without you

That would make "return" in the local scope exit the scope, not the
enclosing function. Which is almost certainly not what people would expect
from a "local scope" statement.
Hence my remark about return and yield requiring attention. These 
would be disallowed in the context of "local:" UNLESS there is an 
enclosing scope of "def function():", so there's no issue of what they 
do if they are simply mainlined, and (I think) a well defined result 
if they are not.
What about getting an untrapped exception? Again, your suggestion would 
mean that only the local scope is exited.  Again, this would be unexpected.
