[Python-Dev] python3k change to slicing

[Neal Becker]

There is one thing I'd like to see changed in a future python.  I always
found it surprising, that
>>> x = [1,2,3,4,5]
>>> x[1:10]
[2, 3, 4, 5]

is not an error.  This is perhaps the only case (but a fundamental one!)
where an error is silently ignored.

I really can't think of a good justification for it.  If I really meant
x[1:]
I would have said so.
