I don't see how anyone could have a hard time using lambdas... they've been around forever, and most programming languages nowadays have them. A good rule of thumb is given by the google python coding guidelines [1]: "Okay to use them for one-liners. If the code inside the lambda function is any longer than 60-80 chars, it's probably better to define it as a regular (nested) function."
