They're intended as the simplest, least obfuscatory examples of using
the walrus operator that is not pointless. That is, an example of the
walrus as a sub-expression embedded inside another expression.
If you think my examples are obfuscated, then that is an argument in
favour of keeping the status quo.
I could have given an example like this:
((a, b) := [1, 2])
but there is no good reason to use the walrus operator there, it is not
a sub-expression, and it Just Works if you use the assignment statement
instead.
