why won't slicing lists raise IndexError?

[Alexandre Brault]

process() wasn't defined either, nor were n and seq and yet you're not 
complaining about them.

It seems it was clear to everyone but you that seq was a sequence 
defined elsewhere, n was an index defined elsewhere, and both process 
and do_without_item were functions defined elsewhere.

And even if you want to be so incredibly pedantic that do_without_item 
(and only do_without_item, because the rest of the code fragment seems 
to get your seal of approval) is not defined, your "functioning 
equivalent" is still not equivalent, because the original code would 
have raised a NameError that yours doesn't.
