[Boost-users] BOOST_CHECK_PREDICATE vs BOOST_WARN_PREDICATE

From: Alex Flint (alex.flint_at_[hidden])

The documentation page for the PREDICATE testing macros gives quite
different syntax for the WARN vs CHECK methods:

    BOOST_WARN_PREDICATE( moo, (12)(i)(j) );
    BOOST_CHECK_PREDICATE( std::not_equal_to<int>(), 2, (i,17) );

Since BOOST_WARN_PREDICATE and BOOST_CHECK_PREDICATE are only slight
variants of one another, I'm confused as to why the syntax differs so much.
Can anyone shed some light on this for me?

Thanks,
Alex
