Because perhaps there is always a good way to compare two data structures
(with the exception of functions) since we can recursively compare their C
representations, but there is not a good way to actually add or even
multiply them.
For exemple it somehow makes sense to compare [] with [2] ( in that case []
< [2] ) but what about [] / [2] ?
