Interesting study on how to adapt OO language syntax to make a language support something similar to XML Schema natively in this paper by Erik Meijer et al of Microsoft Research. Work is extremely concrete, being a suggestion for an actual extension of the C# language. Included is funky native query syntax. This is at least a nice idea, even if it turns out not to be the silver bullet it feels like the authors intended it to be.

TODO : Write the perl source filter that supports these extensions for perl class definitions.
