[Boost-users] Syntax question

I'm trying to static assert the value of a sequence. I've got the syntax 
slightly wrong, but I can't quite figure it out. Here's what my code looks 
like:

==========================
template<typename SEQ, int SIZE>
void assertSeqSize()
{
  BOOST_STATIC_ASSERT(( boost::equal_to<boost::mpl::size<SEQ>::type, 
boost::mpl::int_<SIZE> > )) &&
  "You have attempted to invoke a functor with the incorrect number of 
Arguments.";
}
==========================

The compiler (gcc 3.3.1) tells me:

../../c++/include/functors/ArgList.h: In function `void
   SAGE::FUNCTORS::assertSeqSize()':
../../c++/include/functors/ArgList.h:46: error: parse error before `>' token
../../c++/include/functors/ArgList.h:46: error: template argument 1 is 
invalid
../../c++/include/functors/ArgList.h:46: error: parse error before `&&' 
token

Can anyone tell me my mistake? Did I stick an extra '::type' where I didn't 
need one?

Thanks,
