  * severity:  Showstopper => Problem

Comment:

 The above solution was tested and rejected for the following reason:
 GCC 3.3.3 (which we probably want to support) ICEs if {{{__typeof__}}} is
 wrapped
 into anything while inside a template:

 {{{
 #!cpp

 typedef mpl::identity<__typeof__(1 + 0.5)>::type type; // OK

 template<class T> class A
 {
    typedef __typeof__(1 + 0.5) type; // OK
    typedef mpl::identity<__typeof__(1 + 0.5)>::type type; // ICE
 };

 }}}
