[plt-scheme] how to quote identifier in macro

I've finally had the time to look at this code in more detail.  I'm a
bit confused as to its intent.  When you write:


> ((tata attr vals (self p1 p2) (display self) (newline) (+ p2 a1))  '((a1
> 10)(a2 20)(a3 30)) 4 5)

what are self p1 and p2 supposed to be bound to?  Furthermore, I think
you're trying to mix compile time and run time values (a1 etc.)
