Some proof-reading of the PEP. I apologise if this is out of date.
1) In the beginning of the "Mapping Pattern" section: "{" (pattern ":" pattern)+ "}" This is spelt inconsistently: there is a `+` before the closing `}` but not after the opening `{`.
2) The second code snippet in the "Guards" section:
values = [0]
match value: case [x] if x: ... # This is not executed case _: ... print(x) # This will print "0"
Inconsistent spelling: `values` and `value`
3) At the end of the "Named sub-patterns" section: "PEP 572" It would be more helpful to say "PEP 572 (Assignment Expressions)"
