But if x!() pumps out a constructor, how do you add multiple 
attributes with @GC.NoScan? The constructors would collide.

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;
});
