What did you mean with native? When cx needs to execute a function at compiletime, it links it into a shared object and loads it back with dlsym/dlopen. So while you get a slower startup speed (until the cache is filled), any further calls to a ctfe function run at native performance. Ah okay, but can't Dlang runtime functions not anyway called at compile time with native performance too? So generally, cx first parses the program, then filters out what is a macro, then compiles all macro/ctfe functions into shared lib and execute these macros from that lib? Isn't it better to use the cx compiler as a service at compile time and compile code in-memory in the executable segment (some kind of jiting I think) in order to execute it then. I think the cling repl does it like that. And how does cx pass type objects?

Plus, it means the macro is ABI compatible with the running compiler, so the compiler can pass objects back and forth without a glue layer.
