I'm attempting to (for fun and profit) add the ability to inspect objects in ruby and discover their source code. Not the generated bytecode, and not some decompiled version of the internal representation, but the actual source that was parsed to create that object.

I was up quite late learning about Rubinius, and while I don't have my head around it yet fully, I think I've made some progress.

I'm having trouble figuring out how to do this, though. My first approach was to simply add another instance attribute to the AST structures (for, say, a ClosedScope object). Then, somehow pull that attribute out again when the bytecode is interpreted at runtime.

Does this seem like a sound approach?
