You have a formatting error. You need to move the { to the same line as the let

[sksk]

Yes i know, i mean what are the reasons why it’s not allowed ^^

[Ruckus]

Ah, I see. In that case, I don't know, but this isn't the right channel to ask. Read the channel topic:

All discussion in this channel should begin with a use-case or proposal instead of a question.

I'd guess it's because a newline basically counts as a ;

[karelpeeters]

A puzzler:

val a = longExpressionThatbasicallyTakesUpTheWholeLine
    + 2

[karelpeeters]

I've been bitten by this a bunch of times.

Turns out it's a real one: https://github.com/angryziber/kotlin-puzzlers/blob/master/src/syntax/breakingLines/breakingLines.kts

@karelpeeters Not true. For example, the following requires an explicit ; to avoid exactly what @sksk is trying to do:

val callback: () -> Unit = if (true) {
    test();  // required ;
    { println("yep") }
} else {
    test();  // required ;
    { println("nope") }
}

[Ruckus]

Without the ;, it thinks it's a param to test.

@sksk Interestingly, this works just fine:

_screen?.let()
{
    it.pause()
    _prevScreen = it
}

[sksk]

oh you are right i tested it works fine

[Ruckus]

It may be a bug. You should file it.
