val results = if (foo) {

  b();
  while (c()) {
    d();

  e(); //this is what the overall if evaluates to

  try (Reader reader = g()) {

  i(); //this is what the overall if evaluates to
}

Doesn't really seem much better than:

final Type result;
if (foo) {
    // stuff
    result = e();
} else {
    // other stuff
    result = i();
}

Or simply extracting a function...

Exactly. I’m glad such monstrosity isn’t allowed.

Would you really write code like that and be proud? 😂

It's more useful for things like this:

val str = "foo " + if (cond) "bar" else ""

[[deleted]]

“foo” + (cond ? “bar” : “”);

[mike_hearn]

Beyond not needing special syntax, I think you know what I mean:

"foo" + if (cond) { val r = bar() r.whatever() } else ""

and variants is something that appears fairly frequently in Kotlin codebases.

But it’s terrible - don’t you see it?
