That sounds about right :-)

I don't understand the cases being mentioned in the question, but there are certainly places where lambdas are useful. The most obvious is as arguments to functions that expect functions as arguments.

But yes, even in those cases if a lambda isn't fairly trivial, it probably shouldn't be a lambda.
