Another day, another PowerShell feature discovered. Unfortunately this time it was a feature that made me think I had a bug in my script. The script read through some directories, did some file parsing and created a data object for every directory in the form of a Tuple.

Herb Sutter gave one of my favorite and inspiring presentations. It is called “The Free Lunch is Over”. The original article can be found here. My first encounter though came from his PDC presentation and highly recommend viewing that as well.

There are only a few missing features from our tuple implementation. Mainly FxCop compliance, debugging support and test case code. The actual functional work is complete.

Part 6 left us with comparable tuples. At this point, the Tuple class is functionally complete. There will be a little more done with the debugability and overall fit into larger projects. But otherwise it is sound.

Part 5 produced equality tests for Tuples. This section will add comparison support through the [IComparable](http://msdn2.microsoft.com/en-us/library/4d7sx9hd.aspx) interface. Implementing comparable is very similar to adding equality support. Once again there is a generic class available to make all of the comparison decisions for us; [Comparer](http://msdn2.microsoft.com/en-us/library/cfttsh47.aspx).
