Issue Description:
The following code complains that x is used by a closure before being initialized, instead of more accurately complaining that it's optional-chained (or just generically that it's used):
let x: String?
if [1,2,3].contains(2) {
x = "lala"
}
// else {
// x = nil
// }
print(x)
print(x?.characters.count)
