It might take this approch (interate over the intersect of to AA's)

int delegate(int delegate (inout U, SetT!(T, T)) dg) Intersect(T, U)(T[U] 
first, T[U] sec)

returns this delegate

|{
|  foreach(k, v1; first)
|  {
|    if(v2 = (k in sec))
|      {
|        if(ret = dg (k, Set(v1, *v2))
|          return ret  
|      }
|  }
|}
