Is there a way to make this work (currently scope and join are

__source = source
__join = join

I can get something working by bouncing through global values, but it
looks awful and I think it's a source of a bug due too values being
redefined.
Thanks,

Supply us with just enough source code to actually try it, give the full
error message including traceback, and tell us what you expected to
see. Also tell us Python version (sys.version)
So far you've done none of these. When I try the following, I get no
errors, using Python 2.6.2
class _StreamFactory(object):
@staticmethod
def __call__(lines, source, join=''.join):
class Line(object):
__source = source
__join = join
return Line()
fact = _StreamFactory()
obj = fact(43, "name.txt")
print obj
