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 class="">
so instead of writing:<br class="">
<br class="">
var message: String<br class="">
if x % 2 == 0 {<br class="">
message = "x is even"<br class="">
} else {<br class="">
message = "x is odd"<br class="">
}<br class="">
<br class="">
you can write:<br class="">
<br class="">
let message: String = if x % 2 == 0 { "x is even" } else { "x is odd" }<br class="">
<br class="">
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 class="">
Thanks!<br class="">
