Hi,
Is it possible to test if two range objects contain the same sequence of
integers by the following algorithm in Python 3.2?
1. standardize the ending bound by letting it be the first excluded integer for
the given step size.
2. compare the standardized starting bound, ending bound and step size: two
ranges equal if and only if this triplet is the same.
If that's correct, it would be good to have equality comparison on two ranges.
Further, it might also be good to have sub-sequence test on ranges without
enumerating it.
There's already a discussion about this on python-ideas. But somebody
please tell me, why would you ever need to compare ranges?
It could be useful if you're unit-testing a function that returns a range.
