you can always specify the start, end index:

```
a[start_a: end_a] = b[start_b: end_b]
```

It will fail if the length does not match; or even you can argue 
that it's also runtime error (right, Python is not static 
compiled language).

But the main point I want to make is: these two different 
semantics should have different syntax, do not overload as it 
only confuse the programmer.
