Changes for version 0.02 - 2006-06-05
- Allow hash references to be used as sets, as well as array refs. Acknowledgements to Ken Williams for this suggestion.
- Examples added to the documentation, and corrected the example given in the synopsis.
- Performance boost: store an array [0 1 2 ... n], which is cheaper than constructing 0..$#$list in next().
