It would be useful if the types chose their instruction set by policy.

It would let us handle our own multiple-instruction-sets-in-one-binary needs at whatever level we deem best.
cant be easily added at this level. However, the underlying functor system maybe able to have you write: simd::functor<some_func, sse2_> f2; simd::functor<some_func, sse3_> f3; boost::function<proper prototype> current_f = has_sse3 ? f3 : f2; The main problem is that i am not sure it wont crap out at compile time due to improper intrinsic being used.
