No, actually. But my mistake.
[ a.b() or _previous_ for a in c ]
means
1 or 2 or 3 or 4 or 5
where c= [ 1, 2, 3, 4, 5].
The mistake: thi

You mean like one of these:
def lookahead(iterator):
i = iter(iterator)
x = i.next()
for item in i:
yield x, item
x = item
def lookahead2(iterator, **kwarg):
i = i

'Only' is another known quantifier in logic: 'all and only'. Any

Hi, excellent. Now how about something more generic, possibly:
[ x.y() for x or _next_ in c ]
where the context of _next_ is limited in complexity, and/or can only
occur in a generator?

You are too late, any and all are built-
any( iterab ) and all( iterab )
as shorthand for reduce( operator.or_, iterab ) and
reduce( operator.and_, iterab ).
What do you think?
