So a variable declared in a LOCAL function is still GLOBAL!? That's surprising and it means my function from earlier needs to be messy...

function test()
  local name,stack,duration,timeleft
  if IS_WRATH then
    name,_,_,stack,_,duration,timeleft = UnitBuff(target,n) 
  else
    name,_,_,stack,duration,timeleft = UnitBuff(target,n)
  end
  return name,stack,duration,timeleft
end

because

function test()
  if IS_WRATH then
    local name,_,_,stack,_,duration,timeleft = UnitBuff(target,n) 
  else
    local name,_,_,stack,duration,timeleft = UnitBuff(target,n)
  end
  return name,stack,duration,timeleft
end

wouldn't work of course (those variables being 'local' to that if statement only!
