Nice!
However, the case statements may increase as shown below and I was wondering if
it will still be worth it(Greetings core team!) in adding some syntactic sugar
as aforementioned...
switch cityIDs["Paris"] {
case let .Some(parisCityID) where 0..<3 ~= parisCityID:
print("Paris city ID: \(parisCityID)")
case let .Some(parisCityID) where 3..<5 ~= parisCityID:
print("")
case let .Some(parisCityID) where 5..<10 ~= parisCityID:
fatalError()
default:
break
}
One more aspect that I have thought of is that the proposed switch statement
with optional binding may only bind one value unlike if-let i.e.
if let x = foo, y = bar {
// do something with `x` and `y`
}
// but the following can't happen
switch let x = foo, y = bar {
// compile error
}
