Wait, what? This is actually the opposite of what that policy is for,
no? Adam, I don't blame you, just to get that said first. The question
is: does this policy warning trigger far too often?
What one actually wants is to write
if(arg STREQUAL "OPTIONS")
i.e. arg will get expanded, "OPTIONS" not. Changing everything away from
that pattern will in fact make things worse, and will not help you if I
introduce an xOPTION variable now. So, is this warning too noisy or are
we doing something fundamentally wrong?
