Very hard to say.
LISP has OOP too, Google for CLOS.
Operator overloading is something to avoid anyway, IMHO, just like
static typing is something to avoid if you need fast development, on
schedule and the like.
LISP has one thing that Python does not have: LISP code is LISP data.

That's because the answer depends on lots of context such what is the

question to answer.

Hi,

Which is a _copy_ (via slicing) of part of the list. Another way of
saying this is that it is a _new_ list which has a copy of the
references from the appropriate part of the old list.
