And In case it's not clear why I said that, btw: It's not mere
pedantry. By restating your proposal in those terms, you make it far
broader than a simple textual transformation. Imagine if you'd said it
like this:

"Okay, let's be pedantic. As well as my other proposals, I'm also
requiring that you be able to use 'a+b' as a variable name."

That is most definitely not a simple proposal. And that means it
should be discussed as a much much broader change: disconnecting
keyword arguments from variable names. That should NOT just slide
through as part of a separate change.
