-An immediate effect of this define is the elimination of the need for
-noalias in types <tt>vector<T></tt> and
-<tt>matrix<T></tt>, when assigned to the same type. Although
-this patch implements move semantics for bounded_ and c_ (vector and
-matrix) types, they don't have any effect at those types, due to their
-underlying storage. I included it for possible future exploitation.

+when assigned to the same type. This option doesn't have an effect on
+bounded and c types. Although it is rare, not all compilers support copy
+elision (that allows for move semantics), so a test must be performed to
+make sure that there is a benefit when it is enabled. A small
+demonstration and test can be found in
