Using WPF and MVVM, we have a lot of very useful ViewModels and business objects for reporting. When designing a specific report (so far they're very simple) I'll add the BO/VM as a data source so the report can pull the properties from there instead of having to create and maintain an actual DataTable of properties for each BO/VM. The...

There's a little thing I want to do in Python, similar to the built-in property, that I'm not sure how to do. I call this class LazilyEvaluatedConstantProperty. It is intended for properties that should be calculated only once and do not change, but they should be created lazily rather than on object creation, for performance. Here's t...
