Yes, but I meant given :

#define SOME_MACRO_IN_MY_LIBRARY( variable ) 
do_something_complicated_requiring_type_info_of_type_of_variable

I cannot use boost::type_info<T>() easily can I ?
Granted I could do boost::type_info< BOOST_TYPEOF( variable ) >() but 
that's a bit cumbersome compared to for instance a simple 
boost::type_info( variable ).

Thanks,
