I guess it depends on how concrete the code is. For very general things there just are no good names. I see the point in calling a variable anualSalary, say, but in a function for reversing a list is elementOfList really better than element or than x (which would be my preference)? This, by the way, is probably the main reason math uses single letters for names (with some rules of thumb that hint at the type, like n for an integer, X for a scheme, calligraphic F for a sheaf, etc.).
