Fortunately, Oliver just recently put up a a pdf of his openlazlo slides. Unfortunately there's a lot of blank slides, and rather more diagrams than code. (I think they were limited to 30 minutes, though. Ouch!) What I got out of it was,
- Porting the ActionScript assembler from Jython to Java roughly doubled the LOC for 10x the speed (seems like they use/used Jython 2.0 though, ancient even by Jython standards?)
- Jython's ease of development was a boon during prototyping, but
- Don't be too quick to optimize by re-implementing in Java (or, for CPython developers, C/C++) because "you don't know when you're done prototyping"
