Maybe we're misunderstanding each other then. I'm responding to Sven when he
says:

I.e. all closures will be interface based because there are not enough real
world use cases to support any alternative. Which is contrary to what you're
saying that nested functions/closure will be compatible types. Sven can clear
this up for us I guess.
