Used as the first parameter to the domain<> template. I would have used 
proto::pod_generator<simd_expr>, 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.
