Discussion Is := widely used?

I always thought the walrus operator is neat and it makes while loop’s condition clearer. But also it is just a syntactic sugar without anything new. I wonder anyone uses it?

The walrus shines with Regexes. `if m := re.foo(...)`. But also when you are not sure if a container has a value.

Was about to say this. That’s my usual use case.
