Except the let-else version has one big disadvantage. The 'match' version has bound the error to `e`, so you can log that error or inspect it. The 'let-else' version can't read the error, so its log message can't be as useful. You can't check if it's a specific error, or include the error in logged messages.
It's still convenient, but in really limited circumstances, AFAICT. This week I'll be going through the various Rust projects I maintain at work, seeing if there's useful places for let-else.
