I tried both ways:
boost::mpl::print myvar;
and
template <typename T>
struct print_error {
};
typedef typename print_error::type my_print_error;
my_print_error myvar;
In both cases, the bit in the error in msvc2008 just shows:
1>        with

1>            T=result_type

it doesn't print what that type actually is.
MSVC does this for typedefs except when they are
declared in a class template.  Unfortunately, I don't
know of any way to get MSVC to print the actual type
in other cases.

I've managed to change code a bit to allow for it to be printed at runtime
instead:

throw std::exception(  typeid(result_type).name() )

the error I'm getting is related to a fusion::vector with 1 element only.
I'll post another question about this now.

Thanks,
