That's really not going to work. Yeah, I knew. I was just using it to illustrate my intension. If you #include proto/fusion.hpp, you can use fusion::for_each on the children nodes as follows:
fusion::for_each( proto::children_of(expr), myfunc() );
Yes! Much simpler. All I had to do was define template<typename Child> void xmpl_context::operator()(Child const& a_child) { proto::eval(a_child.*this) } and then in xmpl_context::eval<Expr>::operator()(a_expr, a_ctx) do: fusion::for_each(proto::children_of(a_expr),a_ctx) Thanks.
