1. x! would parse all decls at compile time...
2. all attributes that need to modify the constructor is inserted 
at the points where the x! enabled constructors are 
declared/implemented...

x!("@GC.NoScan @GC.Hot @attribute(Serializable.yes) int value;");

x!(q{this()
{
   /* everything from 'x' is auto inserted here */
   my;
   normal;
   constructor;
   tokens;
});
