I love it!

The difference between holiness and perfection:
---[[
sins = { pride=true; covetousness=true; lust=true; anger=true;
    gluttony=true; envy=true; sloth=true }
    
for k,v in ipairs(t) do if sins[v] then t[k]=nil end end -- holiness
for i=#t,1,-1 do if sins[v[i]] then t.remove(i) end end  -- perfection
--]]

Of course, you must start from an unholy array t!
