This is happening to me multiple times..
I find when and the possibility to declare some val quite limiting:

val platform = when(val os = DefaultNativePlatform.getCurrentOperatingSystem()) {
    os.isWindows -> 0
    
}

if I declare something like that, when expect exclusively matches against os Type
I'd like something more broad

I often have the same problem and it’s a little annoying that I have to introduce another scope.

Your example would be ambiguous though.
Will it evaluate the expression using == or treat it as a boolean?

That’s probably a general problem with when. Some use == (and support partial is …) while some expect a boolean value.

== if type matches, boolean otherwise

like one would normally expect

That would be quite hidden/difficult to see and can lead to subtle errors.
Take Any as an example. Can be == checked against everything.
