+  - TensorRemove is a hack, come up with a long term rationalised approach to Complex vs. Scalar<Scalar<Scalar<Complex > > >
   QDP forces use of "toDouble" to get back to non tensor scalar. This role is presently taken TensorRemove, but I
   want to introduce a syntax that does not require this.
 
+  - Reductions that contract indices on a site should always demote the tensor structure.

+  - Result of Sum(), SliceSum // spatial sums
+              trace, traceIndex etc.. do not.
+
+  - problem arises because "trace" returns Lattice<TComplex> moving everything down to Scalar,
+    and then Sum and SliceSum to not remove the Scalars. This would be fixed if we 
+    template specialize the scalar scalar scalar sum and SliceSum,  on the basis of being
+    pure scalar.
 
 * Optimise the extract/merge SIMD routines; Azusa??
  - I have collated into single location at least.
