Anything that's an immutable sequence of numbers. For instance, a pair of coordinates. Or a value and a weight for that value. > If not, then it's not clear that tuples as a distinct data type > still serves a purpose in the language.

There are countless examples where adding or removing elements from a list just wouldn't be right. > The new intended use is as an immutable sequence type, not a > "lightweight C struct". It's the same, really. A lightweight list of elements, where each element has its own meaning, is both an immutable sequence as well as a lightweight C struct.
