Agree with array/list, we don't need more contiguous chunks of memory, but tuples are very different, if only because they allow elements of different types. They're really more ad-hoc unnamed structs than collections.
in strictly typed languages that would be correct, and I still somewhat agree, but AviatorScript is dynamically typed, and allows lists containing elements with different types. It's basically List<Object>. So it seems to be a strictly semantic distinction.
