Whoops! I forgot to paste in the error text.

/users/ugrad/m/mdw45/465/project1/src/project1.cpp:26: error: no match for 'operator<<' in 'boost::lambda::operator<<(A&, const boost::lambda::lambda_functor<Arg>&) [with A = std::ostream, Arg = boost::lambda::placeholder<1>]((+boost::lambda::<unnamed>::_1)) << std::endl ' */users/user2/ugrad/m/mdw45/lib/format.h:126: error: candidates are: std::ostream& operator<<(std::ostream&, const format&)

It says there's no operator for the expression <<(cout, _1).

No, it says there's no operator<< for (cout << _1) and std::endl. std::endl is an overloaded function and doesn't work with lambda. cout << _1 << '\n' should work.
