As someone who writes a lot of asynchronous code in C++, lambdas have changed my life.

The paper seems to study the use of lambdas specifically as an alternative to iterators. I actually mostly still use iterators myself, rather than lambda-based alternatives, so I agree: they don't have a huge impact there.

But the headline is misleading. It should have had "when compared with iterators" added to the end.
