Last evening I gave a presentation on Groovy to the BCS Advanced Programming Specialist Group. After a short introduction to the history of Groovy in order to set the scene, the session was devoted to showing example code using the Groovy Console. We only had to do some scripting, we didn't really get on to writing classes. It really was a whirlwind introduction.
The session went well. At least I thought it did :-) The organizers must have done as well as they have already asked me if I would do a session on GPars next year.
