The PEP is great, but this strikes me as horribly confusing, given
that 401|403|404 is already legal syntax.
You can combine several literals in a single pattern using
return "Not allowed"
IIUC any legal expression can come between `case` and `:`, but
expressions that contain `|` at their outermost level are interpreted
differently than from in other contexts.
Presumably adding parentheses:
would make it equivalent to
Is a separator (other than whitespace) actually needed? Can the
parser cope with
case 401 403 404:
Failing that IMO preferable, albeit not ideal, possibilities would
1) Use colon as the separator.
2) Use comma as the separator - this is already legal syntax too,
but IMO it reads more naturally.
(And IIRC there are already contexts where brackets are
necessary to indicate a tuple.)
Perhaps someone can think of something better.
I also (with others) prefer `else:` or perhaps `case else:` to using
The latter is obscure, and woudn't sit well with code that already
uses that variable for its own purposes.
