Leak in Lua

[ZiBitheWand3r3r]

Hey, should I set variable u to nil inside ForGroup, or it is not necessary?

function Group_Mixed(g)
local walkers=false
local flyers=false
   ForGroup(g, function()
   local u = GetEnumUnit()
   if UnitAlive(u) then
       if IsUnitType(u, UNIT_TYPE_FLYING) then
            flyers=true
        elseif not IsUnitLoaded(u) then
            walkers=true
        end
   end
   u=nil
   end)
   return walkers and flyers
end

It's unnecessary, the Lua reference counter does not have the same issue as the JASS one.
