 The documentation states:

 {{{
     /// \name Direct factory functions
     /// \brief These functions simply wrap the given data directly
     /// in an Element object, and return a reference to it, in the form
     /// of an \c ElementPtr.
     /// If there is a memory allocation problem, these functions will
     /// return a NULL ElementPtr, which can be checked with
     /// Element::is_null(ElementPtr ep).
     //@{
     static ElementPtr create(const int i);
     ...
 }}}

 But the actual code doesn't seem to handle allocation failure:

 {{{
 ElementPtr
 Element::create(const int i) {
     return ElementPtr(new IntElement(i));
 }
 ...
 }}}

 Am I missing something?  Or does either the doc or the implementation need
 to be fixed?

 I'm giving this to Jelte because I believe he should know this stuff best.
