Does anyone else find trailing lambdas confusing? Especially when learning, I wish I could tell IntelliJ to reformat all code to be explicit about trailing lambdas - it would really help me to understand what is actually going on. Or perhaps a different block delimitator could have been chosen, besides { }, to make it clearer. Or maybe it's just me!

You can always use named arguments if you want.

fun target(lambda: () -> Unit)

//Use it with trail
fun test() = target { println("trailing") }

//Or without it
fun test1() = target(lambda = { println("no trail") })

I personally love trailing lambdas

Once you are familiar with them, they are useful. But when learning a new framework or tool, I'd find it really helpful if IntelliJ could just be a bit more explicit on my behalf. Because otherwise I'm having to guess what the trailing lambda part actually is.

I find rainbow brackets intellij plugin helpful in this regard

Makes it quite visual and easy to spot each lambda scope

Thanks, I'll try it out!

you can use Intellij’s intentions to convert it to an ordinary argument: alt+enter on your trailing lambda
