_1 and _2 are in different domains, but _1(_2) is allowed and is in the domain of _1. That's why the expression "_1(_2) + _1" is permitted, but "_1(_2) + _2" is not.
You might have to post your code for us to get to the bottom of this. Could it come from the fact exponent is just build using
make_expr<nt2::tag::exponent_, domain_of<T>::type, T const&>
and not proto::operator() ?
Oh, you're using make_expr. If the result of exponent(x) is always in the domain of simd_domain<uint_t>, then you should use that as the domain parameter to make_expr instead of domain_of<T>::type. -- Eric Niebler BoostPro Computing http://www.boostpro.com
