There should be only one (defvar <var> <val>) form per variable.
All others should only be (defvar <var>).
Admittedly, this cannot always be done conveniently, but I don't
think the problematic cases happen often, far from it.
Do you have evidence otherwise ?

When have you needed that ?
(I mean actual concrete examples)
