In the context of my software design course, a student did a small project to combine Moose and the Java design pattern detection tool (patterns4.jar) from professor Tsantalis at Concordia university. The code and more detailed explanation is on GitHub at https://github.com/tebo93/PatternParser 

I offered as an optional lab exercise in my course to experiment with Pharo/Moose and there were a small number of students fervently interested. 

Here's a semi-accurate explanation of the workflow in a UML Activity Diagram, using PlantUML:
