I prefere structs to tuples /everywhere/. They have 2 big advantages:
* builtin, well-known, literal notation,
* explicite: color.red versus color[0]

Actually, tuples look only useful to me for multiple return values, when they 
do not build a consistent unit, like (value, error). But I find this bad coding 
style (there is always a better solution, I guess).
