the basic idea is that we encapsulate Objects and primitive types into an API that allows dynamic binding of properties, methods, etc
[09:28] marshall_law: our entire runtime uses the binding API for all exposing
[09:28] marshall_law: so it's basically the common runtime model for Python, Ruby, and Javascript
[09:28] marshall_law: the language runtimes entire job is to adapt their language runtime to our binding API
[09:29] tav: is there any dom specific integration ?
[09:29] marshall_law: we have some custom code that exposes the window object etc back into each language runtime yes
[09:29] marshall_law: we expose window, and document i believe
[09:30] marshall_law: and of course, Titanium)
[09:36] tav: i was going to ask how you handle dom events
[09:36] marshall_law: we don't do anything special for DOM events..
