This has been sitting for a long time. It probably has some problems and needs cleanup. Objects/rangeobject.c now uses 4-space indents since it is almost completely new. ........ r55171 | guido.van.rossum | 2007-05-07 10:21:26 -0700 (Mon, 07 May 2007) | 4 lines Fix two tests that were previously depending on significant spaces at the end of a line (and before that on Python 2.x print behavior that has no exact equivalent in 3.0). ........

A complication is that an iterable and iterator can be the same object. To
maintain the invariant, an iterator needs to dynamically update its length.
-For instance, an iterable such as xrange(10) always reports its length as ten,
-but it=iter(xrange(10)) starts at ten, and then goes to nine after next(it).
+For instance, an iterable such as range(10) always reports its length as ten,
+but it=iter(range(10)) starts at ten, and then goes to nine after next(it).
Having this capability means that map() can ignore the distinction between
map(func, iterable) and map(func, iter(iterable)).
When the iterable is immutable, the implementation can straight-forwardly
report the original length minus the cumulative number of calls to next().
-This is the case for tuples, xrange objects, and itertools.repeat().
+This is the case for tuples, range objects, and itertools.repeat().
Some containers become temporarily immutable during iteration. This includes
dicts, sets, and collections.deque. Their implementation is equally simple
