[boost] [type_traits] is_class not detecting C++0X lambda on Intel 11.1/Windows?

The boost version of is_class doesn't seem to be compatible with lambdas in
my target compiler.  Am I missing something?  Any patches/fixes you can
think of?

Sadly, I can't just use the tr1 version since this is being used internally
within a boost library (boost::parameter in my case).

BOOST_AUTO_TEST_CASE( test_is_class )
{
auto f = [](double x){return x;};
// static_assert(boost::is_class<decltype(f)>::value, "Failure");
//Compiler failure line 81 of boost/type_traits/is_class.hpp
 static_assert(std::tr1::is_class<decltype(f)>::value, "Failure"); //Works
using the built in tr1 for the compiler
}
