    I guess this is related:

    local foo;
    local bar = true;
    if bar then
        foo = 1;  -- This one will be marked as unused.
    elseif not bar then
        foo = -1;

    Thats a dataflow/controlflow analysis problem. It is a separate bug. It need to try it out with foo=false too. There some checking in the control flow analysis for constant conditions. I am curious if it is related to that code or just a bug in if statement analysis
