<br>
I wonder why the Swift compiler does not complain about the<br>
redeclaration of `number` after the guard-statement in top-level code:<br>
<br>
// main.swift<br>
import Swift<br>
<br>
guard let number = Int("1234") else { fatalError() }<br>
print(number) // Output: 1234<br>
let number = 5678<br>
print(number) // Output: 1234<br>
<br>
It looks as if the statement `let number = 5678` is completely ignored.<br>
<br>
However, doing the same inside a function causes a compiler error:<br>
<br>
func foo() {<br>
guard let number = Int("1234") else { fatalError() }<br>
print(number)<br>
let number = 5678 // error: definition conflicts with previous value<br>
}<br>
<br>
Tested with<br>
- Xcode 7.3.1, "Default" and "Snapshot 2016-06-06 (a)" toolchain<br>
- Xcode 8 beta.<br>
<br>
Am I overlooking something or is that a bug?<br>
<br>
