Create an add-on over the memory region for storing tuples.

[marat1961]

Then we could assume that we have a typed region that contains an array of data described by some tuple.
An easy interface for accessing an array of values would be extremely useful.

var 
  meta: TsgTupleMeta;
  rgn: PMemoryRegion;
  tuple1, tuple2: TsgTuple;
  ptr: Pointer;
  pv: PVector;
  ps: PChar;
  pi: PInteger;
begin  
  meta.MakeTrio<TVector, string, Integer>(nil, True);  
  rgn := meta.MakeTupleRegion;
  tuple1 := rgn[5];
  tuple2 := rgn[7];
  tuple1.Assign(rgn[7]);  
  ptr := tuple.tie(0);
  pi := tuple.tie<TVector>(0);
  ps := tuple.tie<string>(1);
  pv := tuple.tie<Integer>(2);
end;
