We have described how single precision checksums can be applied to the iterator testing problem. The technique's ability to detect errors in Lout is measured in terms of its aliasing probability. The time to develop and maintain checksum testing infrastructure is insignificant compared to the time to develop and maintain a typical collection class.
Single-precision checksums can also
be used to test iterators that manipulate non-integer data.
To achieve this, we encode integer values in the elements of 
and proceed as before.
We conclude that single precision checksums can provide cost-effective iterator testing.
