+/** \defgroup membind Bound Member Functions
+
+    The membind() family of function templates simplifies the creation
+    of simple bound member function pointers:
+
+    \code
+      struct Foo {
+          int test(int x);
+      };
+
+      Foo * foo = ...;
+      boost::function<int (int)> f = senf::membind(&Foo::test,foo);
+      int rv = f(1); // Calls foo->test(1)
+    \endcode
+
+    \idea Make the \a ob argument type an additional P template
+    parameter (using call_traits for the exact arg type? Probably
+    we'll get deduction problems then) . The only operation this
+    object must support is ob->*fn. This would allow the use of
+    smart pointers. We should keep the T & version to still support
+    ob.*fn use.
