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?
