1 #### Note: this error code is no longer emitted by the compiler.
3 This error suggests that the expression arm corresponding to the noted pattern
4 will never be reached as for all possible values of the expression being
5 matched, one of the preceding patterns will match.
7 This means that perhaps some of the preceding patterns are too general, this
8 one is too specific or the ordering is incorrect.
10 For example, the following `match` block has too many arms:
14 Some(bar) => {/* ... */}
15 x => {/* ... */} // This handles the `None` case
16 _ => {/* ... */} // All possible cases have already been handled
20 `match` blocks have their patterns matched in order, so, for example, putting
21 a wildcard arm above a more specific arm will make the latter arm irrelevant.
23 Ensure the ordering of the match arm is correct and remove any superfluous
