[karelpeeters]

Yes simple smile. I had the answer still typed up from when you deleted the code.

[Alexey Subbota]

If I write so
interface Sample<in T>{

[karelpeeters]

My bad. You probably do want <in T> on the interface, but that's not the problem here.

[karelpeeters]

The actual problem is that SAM conversion only works for Java interfaces.

Yeah I agree it's weird, the suggestion is to use higher order functions instead.

[Alexey Subbota]

I will
