<p>item = any single argument</p>
<p>When BOOST_VMD_IDENTITY(item) is subsequently invoked with any number of parameters it expands to 'item'. Subsequently invoking the macro is done as 'BOOST_VMD_IDENTITY(item)(zero_or_more_arguments)'.</p>
<p>The macro is equivalent to the Boost PP macro BOOST_PP_IDENTITY(item) with the difference being that BOOST_PP_IDENTITY(item) is always invoked with no arguments, as in 'BOOST_VMD_IDENTITY(item)()' whereas BOOST_VMD_IDENTITY can be invoked with any number of arguments.</p>
