We introduce the following rules for match exprs. - `panic!` and `unreachable!` are treated as consumption. - guard expressions in any arm imply consumption. For match exprs: - Lint only if exacrtly 2 non-consuming arms exist - Lint only if one arm is an `Ok(_)` and the other is `Err(_)` Added additional requirement that for a block return expression that is a match, the source must be `Normal`. changelog: FP [`unused_io_amount`] when matching Ok(literal)
