> You can combine several literals in a single pattern using | ("or"): `case 401|403|404:`

So how do I do a bitwise-or operation within a pattern?

I think given issues like this and the commonly-cited NOT_FOUND example [0], it might have been better to only allow pattern matches on compound data and disallow its use with simple values. That’s where pattern matching is most useful, as in the article‘s second example (`match point`), plus it would make it more obvious that the behaviour of `match` is different from C’s `switch`.

[0] The following code unintuitively assigns the value of status_code to the variable NOT_FOUND:

    NOT_FOUND = 404
    match status_code:
        case NOT_FOUND:
            print("HTTP Not Found")

Edit: OK, it looks like you can’t do arithmetic/bitwise operations in a pattern at all, so there’s no direct clash between bitwise or and this use of `|`.

Therefore if you need to match against a calculated value, you can’t do the calculation inline. Instead you need to calculate the value outside the match and give it a name - but you can’t match against a named local variable either!
