It would be nice to have

it

or similar variable in

else

clause of

when

control structure.

when (a()) {
    1 -> b()
    2 -> c()
    else -> d(it)
}

You can assign in the statement:

when (val res = a()) {
    ...
    else -> d(res)
}

The advantage of this as opposed to assigning a val before the when is that

res

is confined to the scope of the when.

I guess adding an implicit

it

would also break existing code where

when

together with

it

is used in a lambda. btw it's not just a problem with

else

but also the other branches. You don't have the value in the right type there unless you use the preferred approach Ruckus has mentioned.

death to syntax, when should be a method call! so should if

@Ruckus!! I had no idea of that syntax!! Thank you!!
