I'm using it in a buff addon I'm currently working on. Here's a (very) trimmed down version.

local pool
 
local function CreateBuff(pool)
     --create a new control frame
     local buff = ZO_ObjectPool_CreateControl("MyBuffTemplate", pool, parentFrame)
     --do other stuff with buff object
 
     --return it for use
     return buff
end
 
local function RemoveBuff(control)
     --do stuff when you don't need a frame anymore
     control:SetHidden(true)
end
 
local function UpdateBuffs()
     local myBuff
     for i = 1, GetNumBuffs("player") do
          --if a control with this id # doesn't exist yet, create it, otherwise just return the one we have
          myBuff = pool:AcquireObject(i)
          --do more stuff with myBuff
     end
end
 
local function Initialize()
     --create a new pool to get my controls from
     pool = ZO_ObjectPool:New(CreateBuff, RemoveBuff)
     EVENT_MANAGER:RegisterForEvent("MyAddon", EVENT_EFFECT_CHANGED, UpdateBuffs)
end
 
EVENT_MANAGER:RegisterForEvent("MyAddon", EVENT_ADD_ON_LOADED, function(event, addon)
     if addon == "MyAddon" then
          Initialize()
     end
end)
