Hi Gennadiy,

When I use macros such as

         BOOST_CHECK_MESSAGE( !evidence,
                              "update evidence = " <<
withEvidenceUpdate << ", evidence = " << *evidence );

it annoys me that the second argument is evaluated even when the test
should pass.

In the case above, evidence is an optional<int>. It would be cool if the
construction of the error messsage could be delayed until it was
actually needed, to make the above scenario valid.

Do you think that is possible?
