Re: [Python-Dev] (name := expression) doesn't fit the narrative of PEP 20

Wes, sorry, but I really don't follow what you're saying. For example,

[Wes Turner wes.turner@gmail.com]

It displays 3 - while it appears to be silly code, there's nothing about it that's undefined. So I fail to see how showing that example anywhere would do anyone any good.

You can do the same kind of thing today via, e.g.,

class Bindable:
    def __init__(self, value):
        self.bind(value)

    def bind(self, value):
        self.value = value
        return value

    def __bool__(self):
        return bool(self.value)

    def __eq__(self, other):
        return self.value == other

    def __str__(self):
        return str(self.value)

Then:

And I wouldn't put that example anywhere in any docs either ;-)
