I'm writing an app from scratch and I'd like to pay attention to places where I can optimize and profile things. So far I converted a few important functions to SIMD and wrote my own algorithm for another. The other day I got a tip on branch prediction and realized there's more I could learn.

Do you have any recommendations for profiling or optimization?

For example Andrei Alexandrescu likes how much you can do with static if in D however he thinks languages needs to have more powerful reflection.

Jon blow wrote his language so he can both modify the AST during compile time and write compile time rules without writing a plugin

I'd like more errors and warnings to be in a language, such as when I modify array [0] and [2] but not element [1] and extra warnings when I do strange things with a bunch of if's (hard to explain so I'll spare you).

What are yours?
