[Boost-users] [lambda]lambda and lexical_cast

I just wanted to transform a vector of integers into a vecotr of strings,
doesn't seem to be asking much

transform(ilabels.begin(), ilabels.end(), labels.begin(),
lexical_cast<string>(_1));

gcc 4.0.2 doesn't like it at all

/usr/include/boost/lexical_cast.hpp:144: error: 'const class
boost::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost::lambda::bitwise_action<boost::lambda::leftshift_action>,
boost::tuples::tuple<std::basic_stringstream<char, std::char_traits<char>,
std::allocator<char> >&,

'fail'

<begin polemic, use flame retardant>
Is it only me or does lambda lack orthogonality with anything else? Whenever
I use lambda for anything non isomorphic to the the plain vanilla examples,
the compiler goes ballistic
<end polemic>

Thanks
