If the compiler produces a program that doesn't match your description, you can debug the compiler. Can you debug an LLM?
Well, remember, a code smell isn't something that's inherently bad, it's "a hint that something might be wrong".
I'm not saying that anyone should flag lambdas as a problem in code review, just that when you see one, it's probably worth taking a second to ask yourself if a named function would make more sense.
I appreciate that this article highlights the value of using of named functions in functional-style code. Too often, programmers assume that "functional programming" means using lambdas everywhere, when in my experience, lambdas are actually a (very mild) code smell.
