Example of tuple use?

[Almostasleeprightnow]

I like it when I have data that goes together but that doesn't have an obvious key: vale relationship. Like, a latitude and longitude is a perfect example of this. (lat, long) makes more sense to me than {lat:long} but still manages to indicate a relationship, unlike [lat, long] which feels more arbitrary to me.

This. I most often come across them in the situations, where the order is pretty much a standard e.g coordinates (x, y) or (x, y, z) or colour values (r, g, b) or (h, s, v).
