sure, one could perform all sorts of analysis on the code.
but i think that would be beside the point.  i find that code that is subtle
enough to evoke a warning often needs to be simplified
for the benefit of other humans — or even the author in
a week.

in your case, you can either provide a dummy assignment
or use SET(var) to inform 8c that it can forget about that
warning.
