want to have something like

fun funGenerator(some flags) { if flag = a return fn(param) { some operation on param }
if flag = b return fn(param1 param2} {some different operations } }

first of all define return type, as I mentioned in another thread, also, usually easier to use lambda instead of anonymous function

[gildor]

hah, funny, actually, for your case anonymous function is just fine, because do not clash with when block:

fun funGenerator(flag: Int): () -> Unit {
        return when (flag) {
            1 -> fun() { /* Do something for flag 1 */ }
            2 -> fun() { /* Do something for flag 1 */ }
            else -> error("Unknown flag")
        }
    }

That's exactly the kind of stuff I'm trying to move out of a different function. Thanks, I can work with this

[Niels Renard]

Thought Unit was just for returning void

[gildor]

Kotlin doesn’ have void, so yeah, use Unit or any type which this function should return

[gildor]

you also can use lambdas instead, anonymous function is very rare thing on my practice

[pakoito]

are local functions expressions?

[pakoito]

or statements

[gildor]

Expressions. Local anonymous function is almost the same as lambda, the biggest difference is that you can use return inside of anonymous function

[pakoito]

yeah they get compiled as lambdas, I didn’t know you could also assign them to a variable. We JS, guise.

[Niels Renard]

ended up rewriting them as lambda's. lot cleaner
