I'm also studying file iteration so I can see if that
helps me out.

Please do adopt this strategy.  Currently this kind of
code doesn't work:

BOOST_TYPEOF_REGISTER_TYPE(
    boost::mpl::math::string_c_to_double
  , BOOST_MPL_PP_ARG_SEQ(unsigned char, 40)
)

BOOST_MPL_PP_ARG_SEQ uses BOOST_PP_REPEAT to create a
sequence of N elements containing the specified
primitive integral type.

I'll make use of them when I get the chance.
