There is no confusion. I am aware that the 'default definee' (current
class) at top-level is Object and that this is different to the self at
top-level which is main.

I know.

You're only half-right here. Default definee determines what 'def' works
on, but not include. At top-level 'include' is actually a singleton
method on main (see method(:include).owner) and its definition is
top_include() in eval.c where it explictly includes the module into
Object (did you read the blog post i linked earlier...?)

Ok. But i'm not debating this. :)

I don't know what you mean here. I was talking about the ivars on Object
- the *class* called Object. Classes can have ivars too, as im sure
you're aware: e.g:

class Hello
  @x = 10
end

And these ivars ARE defined on an iv_tbl in the class (or at least on
the  rb_classext_t member in the class).

I think we have been mainly talking at cross-purposes here. I do not
disagree with a lot of what you have said but I also do not see how it
is relevant. The point I was making was that:

(1) 'current class' and 'cref' at top-level are Object anyway, so
methods and constants will end up on Object.

(2) the top-level include method, although it is defined on main
(singleton class) actually includes into Object. Same with top-level
public and private methods.

(3) Instance variables, in so far as they're used (which i cant see what
for, really) may as well just be defined on the Object class (i mean
class instance variables here)

So i thknk if you just made Object the top-level context rather than
'main' you would get (1) and (2) for free (wouldn't' have to define any
weird singleton methods a la 'include') and (3) you may as put the ivars 
on
Object class, ii can't really see any reason why not to :)
