Hrm, OK, that makes sense. Thanks for taking the time to explain! Guessing optimizing x+y*z would entail something similar to the third eval() definition but with Expr<L, Expr<L2, R2, Mul>, Add> instead. I think at this point I can see how my initial assertion was wrong - specialization isn't fully orthogonal to expression templates, as the former is needed for some of the latter's use cases. Does make me wonder how far one could get with rustc's internal specialization attributes... |
