-Note that dereferencing a ``Value::use_iterator`` is not a very cheap operation.
-Instead of performing ``*i`` above several times, consider doing it only once in
-the loop body and reusing its result.

 Alternatively, it's common to have an instance of the ``User`` Class (`doxygen
 <http://llvm.org/doxygen/classllvm_1_1User.html>`__) and need to know what
 ``Value``\ s are used by it.  The list of all ``Value``\ s used by a ``User`` is
