[Cuis] 4.1 to 4.2 migration question

[Casey Ransberger]

If memory serves (and it may not) Igor mentioned having automatically generated bindings based on the API at one point when I asked about it. The comment in there made me suspect that you might be adapting generated code that he'd had his hands in. Might be worth asking him. 

One reason I'm interested here is, the Croquet stuff isn't just tangled up with a synched messaging model, it's also written in a style of GL that doesn't really seem to be supported anymore. So automatically generating bindings for something like e.g. OpenGL ES on the Pi is really compelling right now. 

One comment inline.

Hmm. And that worked with this stuff in 4.1? Seems odd to explicitly call out the default parser. Might be worth looking at what comes back in Squeak and (gut says) Pharo to be sure.
