I really like this style of programming, especially after fooling around with Rust a lot, where pattern matching and its variations, like "if let" are working really well.
I also like the idea of using the walrus operator in this use case, while it is probably up for a lot of discussing if the walrus operator should/can be reimplemented like this. With this pattern matching movement (PEP 622, 634, 636) this idea fits right in. A downside IMO is the readability. In the patter matching proposed in PEP 636, we introduce verbosity, while preserving readability. Every case is clearly readable. In your example I had to look twice that the 'Response' is the pattern which is matched from the 'get' result. But in the end this argument also applies to the already implemented walrus operator, so there is that.
