I think we are conflating (at least) two different issues here because we don't have a good way to deal with them separately. Closure on one hand and implicit logic on the other.

Most of the time when I split out a method what I want is a closure that is clearly separated from the rest of the code. If I can have such closures, where input and output is clearly scoped, without defining a new method, that might be preferable. Lambdas could be one way to do it but they still inherit the surrounding closure so it's typically not as isolated as a method.
