A modern programming language that makes developers happier.

kotlinlang

if `callButtonState` isn’t just an `Int`, sure, I guess, but why would this need to be exhaustive? these methods look like they’d return `Unit`, so the `when` doesn’t look like it’s assigning anything useful

I see your point, the question was just seeing if its possible

actually its what should happen after a button click, (and yea its enum, just int for speed writing the pseudocode)

it’s just that I can’t think of a case where you would both need to be exhaustive and have a branch that does nothing and therefore be cool with the fact that the when implicitly returns `Any`

you wanna eliminate the `{}` when Kotlin lets you eliminate the case entirely

but then it will complaing about it not being exhaustive

`when` is only required to be exhaustive when used as an expression

say I have enum { FOO, BAR, NONE } .. when(foo) ..

oh I see, it’s _recommended_ to be exhaustive

..I still get warnings, even I am not returning from when

that’s a weird thing to have enabled by default

I honestly like it, but that formatting messes up niceness of code for me :smile:

but I guess could have noop: Unit function

you may as well just have `case -&gt; Unit`

yea, because now when I thing about it, if when is expression I would need to return something anyways, not just Nothing, okay thanks

I guess technically speaking the JB guys would rather you use an if/else if for this kind of scenario but I still think it’s dumb lol

I wont since I dont have ternary operator lol
