Solidity feature request: macros

[nmushegian]

I want this:

#define PROD false
#define DEFAULT(TYPE, ADDR) #if PROD TYPE(ADDR) #else new TYPE() #endif
#define LOG(what) #if PROD ; #else log(what) #endif

and so on. Don't tell me it's unsafe, I'm gonna use gcc to do it if you don't!

if macros are considered I would suggest something like rust's macro_rules!

// This is the simplest macro, `say_hello` is the name of the macro
macro_rules! say_hello {
    // `()` indicates that the macro takes no argument
    () => (
        // the macro will expand into the contents of this block
        println!("Hello!");
    )
}

Yes, I would also prefer a token-based macro system like the one used by rust.

+1 for native macros instead of preprocessor based. Rust's macros are not particularly nice though, we could do better.
