Yes, I confirm your code seems to indicate that the loophole allowing
member variable access of an object from another object's method has
been eliminated. I would count that as a bug fix, but I wish it had been
mentioned in the release notes. I think there is going to be some broken
code that will need to be updated for IDL 8.2.

Also, note that by making obj2 inherit from IDL_Object will make the
code work again on IDL 8.2, i.e., update obj2__define to:

pro obj2__define
compile_opt idl2
obj2 = { obj2, inherits IDL_Object, index:0L }
end
