Oh, I see that you indeed implemented a macropy version at https://github.com/boxed/macro-kwargs/blob/master/test.py. Other than use() vs grab() as the function name, it's the same thing. Is it true that the macro version has no performance cost? So it's now perfectly straightforward to provide both a function and a macro for grab(), and users can play with that API, right? Without changing Python, programmers can use this "shortcut keyword arguments corresponding to local names." On Wed, Sep 26, 2018, 5:31 AM David Mertz <mertz@gnosis.cx> wrote:

I saw now that I missed the biggest problem with your proposal: yet again
you deliberately throw away errors. I'm talking about making Python code _less_ error prone, while you seem to want to make it _more_.
Beyond the belligerent tone, is there an actual POINT here?
Yes, there is a point: you keep insisting that I shut up about my ideas and you motivate it by giving first totally broken code, then error prone and slow code and then you are upset that I point out these facts. I think it's a bit much when you complain about the tone after all that. Especially after you wrote "If someone steps out of line of being polite and professional, just ignore it" the 9th of September in this very thread.
That's fine. I'm not really as bothered by your belligerent tone as I'm trying to find the point underneath it.
I guess... and I'm just guessing from your hints... that you don't like the "default to None" behavior of my *TOY* code. That's fine. It's a throwaway demonstration, not an API I'm attached to.
You're new here. You may not understand that, in Python, we have a STRONG, preference for doing things with libraries before changing syntax. The argument that one can do something using existing, available techniques is prima facie weight against new syntax. Obviously there ARE times when syntax is added, so the fact isn't an absolute conclusion.
But so far, your arguments have only seemed to amount to "I (Anders) like this syntax." The supposed performance win, the brevity, and the hypothetical future tooling, are just hand waving so far.
