I did. Twice. It means little to me. The PEP makes too many assumptions 
about the reader's understanding of the issues involved.

If this was a proposal for a new library, I'd say "It doesn't effect me, 
I can ignore it, I just won't use the library". But you're talking about 
adding syntax and changing the execution model of Python. This becomes 
part of the language.

I'm not hostile to the idea. But the PEP needs to reference concrete 
examples that people can run to see that there is a problem to be 
solved. Otherwise, it just seems that you're proposing adding more 
complication to the Python, at least one new keyword and one more 
builtin, for what gain?
