Re: custom functions or function macros

=D I like that someone else said bundles are not functions, thanks Mike.
=D

As Mike noted, we don't yet have any way to define custom functions
(though we do have custom promise types now!) and none of our [existing
macros] speak to this kind of functionality, they are all more about
including or excluding a block, not for filling in the content of a
block with some referenced content..

If you are repeatedly using `not( strcmp( host2ip( $(hostname) ),
$(hostname) ) )' I think the typical approach would be to simply define
a class and use that.

,----
| bundle agent __main__
| {
|   vars:
|      "hostname" string => "localhost"; 
| 
|   classes:
|       "hostname_does_not_match_ip"
|         scope => "namespace", # Presumably we want to use this in other bundles
|         expression => not( strcmp( host2ip( $(hostname) ), $(hostname) ) );
| 
|   reports:
|       hostname_does_not_match_ip::
|         "hostname '$(hostname)' does not match to an ip address because '$(hostname)' does not match '$(with)'"
|           with => host2ip( $(hostname) );
| 
| }
`----
Listing 1: Example Policy

,----
| R: hostname 'localhost' does not match to an ip address because 'localhost' does not match '127.0.0.1'
`----


But, maybe you have some other reason why you are using the nested
functions calls repeatedly instead of using them to set a class once.
