That's actually what I was going for, except I was modeling it after range, but
that was the only way I knew to implement it.

Wouldn't it be better if it has the same signature(s) as itertools
Just some dribble, nothing major.
I like using slices but I also noticed that a slice expression returns a new
sequence.
I sometimes find myself using them in a for loop like this:
seq = range(10)
for even in seq[::2]:
print even
(That's just for an example) But wouldn't it be a bit of a
...oh and here is the class I made for it.
class xslice(object):
'''
xslice(seq, start, stop, step) -> generator slice
'''
def __init__(self, seq, *stop):
if len(stop) > 3:
raise TypeError("xslice takes at most 4 arguments")
elif len(stop) < 0:
