Preparatory work for union literals

Contains horrible parsing hacks that transmute function calls and
enum literals to union literals if appropriate. Pending the
implementation of the tokenizer the AST can be constructed more
neatly.

    (false, $name:literal, $format:literal) => {};
    (false, $name:literal, $format:literal, $($args:expr),*) => {};
    (true, $name:literal, $format:literal) => {
        println!("[{}] {}", $name, $format)
    };
    (true, $name:literal, $format:literal, $($args:expr),*) => {
        println!("[{}] {}", $name, format!($format, $($args),*))
    };
}
