+1. This is example *is not* a single expression code block. There are 3
expressions (the condition, the return value in the else block, and the primary
return value).
The `else` block is a returning single expression block. I can’t show the
`guard` example without any returning scope.
You said it yourself "everywhere in the language“. It’s not “everywhere“ if we
would left out `guards` else-returning block.
If we’d allow this we could also write:
func test(boolean: Bool) {
guard boolean else {}
print("true")
}
This is useless and less readable.
But we already can do this with closures:
let nop = {} // useless
switch value {
...
default: {}() // do nothing
}
