Will do.

[orangy]

The root cause is that in resolves to different contains with smart cast and without

[jlleitschuh]

The weird thing about this example here is that with two different call's to thing you are getting two different values.

if (thing != null // This could evaluate to `true`
        && 
        thing in list // `thing` can be null here.
        ) { // fails
        
    }

[orangy]

yes, exactly, that’s why smart-cast doesn’t work

[jlleitschuh]

It's a convoluted use case and probably not what the developer means, but it should compile regardless.

[orangy]

It will be the same with a simple var, because it can be modified on a different thread

[diesieben07]

Yes, I don't know why I put that random thing there.

[diesieben07]

It's not relevant to the issue at all.
