If loops can have specialized control-flow keywords (break; continue), why not let match have one (fallthrough)? match x { 0 => { /* do some stuff

If loops can have specialized control-flow keywords (break; continue), why not let match have one (fallthrough)?
match x {
0 => { /* do some stuff */; fall_through; },
1 => true,
_ => false
}
However, I don't know yet how useful it would be. I can't remember ever really needing it, so it would probably need a few practical examples before it became a reality but its an idea.
- pcwalton 11y agoIf we really need it I'd rather have C#-style goto-label instead of explicit fall-through, which is strictly less general. (But I'd almost rather it be a tail-duplicating macro to begin with, since the feature is so rarely needed.)
