<br>
It would be cool if control flow statements like "switch", "if" can be used as expressions, such as in languages like Scala, Rust and Kotlin,<br>
so instead of writing:<br>
<br>
var message: String<br>
if x % 2 == 0 {<br>
message = "x is even"<br>
} else {<br>
message = "x is odd"<br>
}<br>
<br>
you can write:<br>
<br>
let message: String = if x % 2 == 0 { "x is even" } else { "x is odd" }<br>
<br>
I'm not into any kind of compiler development, and don't know is it feasible to introduce such change at the moment, but at least, I would like to hear why not.<br>
Thanks!<br>
