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.
