[Laszlo-dev] still confused about referencing node id's from methods

[P T Withington]

That's a huge change from JS1.  There must be some way to do this.

Supposedly there is an 'unnamed package' whose top-level definitions  
are accessible to the entire program.  So we just have to figure out  
how we put our global definitions there.  I'm not creating any  
`global` object, just setting properties on it, so I was assuming that  
`global` was an alias for this unnamed package.

I would think you would get an error trying to install the global  
property if that were not true.

Maybe I don't understand about creating globals dynamically.
