Neat code indeed. What's the simd_generator class ? a context or something I miss ?

Used as the first parameter to the domain<> template. I would have used proto::pod_generator, except that the pod_generator<> template accepts only class templates with one parameter, and simd_expr has two. See the section in the docs on generators ... they're just function objects that return wrapped Proto expression objects. -- Eric Niebler BoostPro Computing http://www.boostpro.com
