Hello!

I don't sure, that I choose right mail list for my ofer... So, don't 
beat me much... :)
I often use such macro for testing function parameters:

#define THROW_INVALID_ARGUMENT_IF_FAIL(expression)                   \
do {                                           \
    using std::invalid_argument;                           \
    using std::string;                               \
                                           \
    if(!(expression))                               \
        throw invalid_argument(string(BOOST_CURRENT_FUNCTION) +           \
                       " : Assertion '" #expression "' failed");  \
} while(false)

I think, that this macro is very useful and can be part of 
<boost/utility.hpp>.
