Hello, I am trying to return a lambda with a receiver from a when statement, but it doesn't seem to work, the receiver does not register. How can I make this work?

[Marcin Wisniowski]

I was assuming the compiler would infer the type of the lambda based on the specified variable type. But it does not.

try adding more `{}`s

Max meant adding another layer of curly braces around the cases of your when expression.

[Marcin Wisniowski]

Ohh, I see. Makes sense in retrospect. Thank you.

[nanodeath]

sorry I had a surprise call

[nanodeath]

yeah -- foo -> { println("") } usually means "execute this multiline block", not "I'm returning a lambda" 🙂

[ribesg]

I think -> ({ copy(a = true) }) would make it more clear that you return a lambda as a value than double braces

[nanodeath]

ah, hadn't thought of that. good point Gael

So would wrapping your assignment expression in ( ) make it an expression within a higher order function!?

Please pardon my ignorance brand new to kotlin

[ribesg]

Assignments are not expressions in Kotlin.
