It's actually shorter to keep the constant string but not assign type to 
a local, since it's only called once - at 238:

local k,d=next d=function(a,r,t)if"table"~=type(a)then return a end 
t={}r=r or{}r[a]=t for x,y in k,a do a[r[x]or d(x,r)]=r[y]or d(y,r)end 
return t end table.copy={shallow=function(a,b)b={}for x,y in k,a do 
b[x]=y end return b end,deep=d}
