Correct.

Same here.

Almost. With << and >>, the numerical prefix is the number of lines
to operate on, not the number of times to repeat. (I don't know why
it is different from all other commands) Nonetheless, type >> once
and then, for example, 3. to repeat the command three more times.

Let's not mention the time I spent far too many hours trying to debug
this piece of C++ code :
while (item = list->next()) ;
{
cout << *item ;
}
The list is empty the first time this piece of code is reached. The
program crashes (SEGV) every time, on the line with the 'cout'
statement. Can you see the problem? The same typo in python would
result in a quickly-found syntax error.
In practice the "lack" of braces solves more problems than it creates.
If you want proof, then try it! :-)

PS. I don't remember the exact spelling for getting the next item
from an STL list, but it is similar enough to what I wrote above.
PPS. The list returns NULL when trying to access elements beyond the
end of the list.
