Recursive AS-Macros

Actually, they're already in all PRIDE tools and software. Here's
one in the RIPE RR.
% whois -r AS-NORDUNET
as-macro:  AS-NORDUNET
descr:     Macro with all ASes exported by NORDUnet
as-list:   AS-SUNET AS3224 AS2603 AS1654 AS224 AS1835 AS1850 AS1741 AS1739
as-list:   AS544 AS719 AS565 AS2847 AS2380 AS3221 AS2588 AS1887 AS2895
as-list:   AS3240 AS1248
guardian:  staff at sunet.se
tech-c:    Bjorn Carlsson
admin-c:   Bjorn Eriksen
changed:   bc at sunet.se 940921
source:    RIPE

There is even a small PRIDE tool called maxpand to recursively expand these. 

% maxpand AS-NORDUNET
AS224       AS544       AS565       AS719       AS1248      AS1653  
AS1654      AS1739      AS1741      AS1835      AS1850      AS1887  
AS2380      AS2588      AS2603      AS2831      AS2832      AS2833  
AS2834      AS2835      AS2836      AS2837      AS2838      AS2839  
AS2840      AS2841      AS2842      AS2843      AS2844      AS2845  
AS2846      AS2847      AS2895      AS3221      AS3224      AS3240  

I guessed I missed adding it to the text. I will add this in.

  * How about allowing AS-Macros to contain AS-Macros.  E.g.:
  * 
  * as-macro:  AS-MCI
  * descr:     All MCINet ASs
  * as-list:   AS-MCI-EAST AS-MCI-MIDWEST AS-MCI-WEST
  * 
  * as-macro:  AS-MCI-MIDWEST
  * descr:     MCINet ASs with primary routes through CHI NAP
  * as-list:   AS233 AS237 AS266 AS267
  * 
  * as-macro:  AS-MCI-EAST
  * descr:     MCINet ASs with primary routes through NY NAP
  * as-list:   AS560 ...
  * 
  * ...
  * 
  * This would require a couple of words change on Appendix C, "as-list"
  * description (plus possibly some code modifications).  This may be
  * particularly useful for simplifying the complexity of representing
  * policy in *both* AS-IN and INTERAS-IN formats.

  * (Or, of course, this extension could be handled with whatever normal
  * mechanisms will be used for additions to RIPE-181 after tomorrow.)
