+Overloaded name
+    Overloaded name is a term used in this reference documentation to designate
+    a metafunction providing more than one public interface. In reality, 
+    class template overloading is nonexistent and the referenced functionality
+    is implemented by other, unspecified, means.

+Concept-identical    
+    A sequence ``s1`` is said to be concept-identical to a sequence ``s2`` if 
+    ``s1`` and ``s2`` model the exact same set of concepts.

+Bind expression
+    A bind expression is simply that |--| an instantiation of one of the |bind| 
+    class templates. For instance, these are all bind expressions::
+    
+        bind< quote3<if_>, _1,int,long >
+        bind< _1, bind< plus<>, int_<5>, _2> >
+        bind< times<>, int_<2>, int_<2> >
+
+    and these are not::
+
+        if_< _1, bind< plus<>, int_<5>, _2>, _2 >        
+        protect< bind< quote3<if_>, _1,int,long > >
+        _2
