It's worth noting that there's a truly massive amount of precedent in other languages for Python implementing it using the syntax as proposed. Languages that have or are planning to include pattern-matching where the pattern syntax exactly mirrors the expression syntax like this include Rust, Swift, OCaml, Haskell, C++, Ruby, Erlang, and many, many more. I understand the worry that newcomers might struggle, but I don't think it's going to be the case: newcomers regularly learn the languages listed above without stumbling across that problem. And if Python did choose a syntax like the one you're proposing, it'd also be the odd one out among dozens of mainstream languages including this feature, which I think would be even more confusing!
