Yes, I see a lambda as an anonymous function and not as an abstraction
over a statement or an expression.
That's why 'return' returns from the lambda and not from the function.

In my opinion, lambda are more like anonymous class but for function.
So like you use Outer.this in an inner class to access to the enclosing 
class,
you should use f.return to return from a named function in an anonymous
function.
