That seems to be *the point*. Although list(a) + list(b) could create a list [ a[0]+b[0], ...] and bail out if for elements '+' is not defined... > Python doesn't have built-in mathematical arrays, otherwise known as > matrices.

Well I am aware of that but I don't understand the reasons of having both lists (which are infect arrays) and *arrays ? *I* would rather drop '+' and '*' to work like they do in *array ...
