Example of what? How is this any simpler?

-------------------------------------
const lest::test specification[] =
{
    "Empty string has length zero (succeed)", []
    {
        EXPECT( 0 == string(  ).length() );
        EXPECT( 0 == string("").length() );
    },

    "Text compares lexically (fail)", []
    {
        EXPECT( string("hello") > string("world") );
    }
};

int main()
{
    return lest::run( specification );
}
------------------------------------

vs.

BOOST_AUTO_TEST_CASE( my_test )
{
    BOOST_TEST( 0 == string(  ).length() );
    BOOST_TEST_MESSAGE( 0 == string("").length(), 
                        "Empty string has length zero (succeed)" );
    BOOST_TEST_MESSAGE(string("hello") > "world",
                        "Text compares lexically (fail)" );
}
------------------------------------

Not only Boost.Test version is simpler, it is also smaller, easier to 
understand, easier to extend, more flexible and provides better output in 
general. On top of than it simply does not look weird with all these [] {} 
spread all over your example. And I am not talking about all the other 
features UTF has, that this library does not even come close to replicate.
