This isn't really true:
s.index(x[, i[, j]])
return smallest k such that s[k] == x and i <= k < j
same as s[i:i] = [x]
However, I don't think this naturally extends to slices:
for index, there is no <= relationship for slices (atleast
not a natural one), and for insert, you can use slices as
start- and end-index of a slice.

Right. For UserList, it probably falls out naturally.
