I've been to three OSCON's, one YAPC::EU, but this is my first workshop and so far I'm having a blast. It's short enough that burnout doesn't seem to be the same factor as one has with OSCON, but it's packed chock full of information. So far, the talks have been good, as have the speakers, and they provided the best lunch I've ever had at a Perl event.
The one thing I'm wondering about now, for Perl 6, is how $object.can($method) is implemented. If an object can do a a particular method name, it does guarantee that it has the same signature. I can grab a method object and introspect it, but that's harsh. Time to hit the mailing lists.
My own talk, by the way, seriously needs updating. At the time I pitched it, there were several ways to run test suites written in multiple languages. I could have spent a lot of time covering the various strategies, including the --execrc switch, which was effectively me using YAML as a domain-specific language for running tests. That seemed awful to me, and it was complicated, so I killed all of the other ways except for the --exec switch. Now I can explain how to run multi-language test suites in a lightning talk instead of a full presentation, so I digressed a bit into the history of TAP and how it compares to XML for suitability for it's task. I need to repitch my talk for Vienna now.
