I think in certain situations the walrus operator will probably be useful. But it definitely makes code less legible, which makes me cautious. The only useful use case I have found so far is list comprehensions where some function evaluation could be reduced to only one execution with the walrus operator.

Just yesterday I wrote code of the form: foos = [] foo = func(a,b,c,d) while foo: foos.append(foo) foo = func(a,b,c,d) With the walrus operator, that would just be: foos = [] while foo := func(a,b,c,d): foos.append(foo) Further, I had to pull out 'func' into a function in the first place so I wouldn't have something complicated repeated twice, so it would remove the need for that function as well.
