Group Data Objects into Tuples

Primitive datatypes such as integers, floats, booleans, and strings are useful but often not sufficient. Yet, when modeling real-world phenomena, we often need to glue together data to form compound data. Consider the example of developing a software package for 2D graphics. To represent, say, a point we could use two separate float numbers denoting its x and y coordinate. But this could get messy because we would need to keep track of what x and y coordinates belong to what point. It’s much better to glue an x and y coordinate into a compound data object like a pair and treat the point as a single concept.
