[self-interest] macro systems

[James McCartney]

The best reference would probably be the book _On_Lisp_.
(Which I just discovered you can download for free from 
http://www.paulgraham.com/onlisp.html  )
A macro is basically a way to run language code at compile time to 
generate language code.
With this you can do any kind of stitching together of concerns that 
you would want.
If you wrote a set of macros to create your classes you could have them 
generate code for your methods,
including any 'aspect' like concerns.
