BTW, matlab has 1-based indexing too. Maple has both: there is an
array object that can be 0,1,2,... based and a List object that is
1-based. I think it would be nice to have an iterator object similar
to (1:n) in matlab (but not a list object).

How about providing a sum function that would behave like, say, the
integrate function. It could detect the argument types so if you
passed it a list, it'd behave the same as the builtin sum function.
sage: integrate(x, x, 0, 10)
50
sage: sum(x, x, 0, 10)
55
sage: sum(range(10))
45
