[Boost-users] [mpl] Syntax error with BOOST_MPL_ASSERT

What's wrong with this ?

template<class Expected, class T>
void check_placeholders(const T&) {
   BOOST_MPL_ASSERT((is_same<typename T::placeholders, Expected>)); // *
}

struct Test {
   typedef int placeholders;
};

void f() {
   check_placeholders<int>(Test());
}

msvc9 complains about : error C2059: syntax error : ')' at the line 
marked with a star. I have put much more complex things inside 
BOOST_MPL_ASSERT though :-/

I use Boost 1.40.
