Hi all!
New variant of BOOST_ENFORCE macro:

#define BOOST_ENFORCE(expression)                      \
do {                                           \
    if(!(expression)) throw std::invalid_argument(                   \
        __FILE__ " : " BOOST_STRINGIZE(__LINE__) " : "               \
        + std::string(BOOST_CURRENT_FUNCTION) +                   \
        " : Expression '" #expression "' failed");               \
} while(false)

And few question about it:
1. How to escape converting BOOST_CURRENT_FUNCTION to std::string? Is 
there way to get function name as string literal?
2. Is line number useful information? I think, that filename and 
function name is good enough.
3. Any observations and suggestions?
