I asked this on boost-users with no luck, so I figured I'd kick it up
to the experts:

I'm trying to use the 3-argument version of the mpl::at metafunction,
as described in the on-line manual, but I'm getting a compile error
(using gcc 4.0.2):

error: wrong number of template arguments (3, should be 2)
/usr/include/boost/mpl/at_fwd.hpp:20: error: provided for
'template<class Sequence, class N> struct boost::mpl::at'
Looking at at.hpp, at_fwd.hpp, and aux_/at_fwd.hpp, I don't see any
sign of a 3-argument version of at; everything seems to be defined in
terms of a 2-argument template. Am I doing something wrong, or is this
a bug?
