- *slicing*:
the slice start must be within bounds. The stop doesn't need to, but it
must
not be smaller than the start. All negative indexes are disallowed,

+ the [:-1] special case. No step. Slice deletion follows the same rules.

+ - *slice assignment*:
+ only supports ``lst[x:y] = sublist``, if ``len(sublist) == y - x``.
+ In other words, slice assignment cannot change the total length of the
list,
+ but just replace items.
- *other operators*:
``+``, ``+=``, ``in``, ``*``, ``*=``, ``==``, ``!=`` work as expected.

* stackless and JIT integration
