I use OCaml and I think of it as idiomatic naming for pattern matching on a list, in a similar way to how iteration variables are often named `i`, although `index` might be more superficially clear, but in reality it is not really since one "knows" `i` is the interation variable, just like `x::xs` means `x` is an element and `xs` is a list of x'es, that is elementy of the same type as x. Pretty clear in my opinion.
