Puppet users - May 2007 - regex in case statement

I would like to do a case statement based on different vlans. If a person does a
case statement on $ipaddress provided by facter,
can you match regex expressions such as 

case $ipaddress {
   "192.168.1.[0-9]+":
      do something
   "192.168.2.[0-9]+":
      do something else
}

Also, would this best be solved by a case statement or other functionality
within puppet?

Thanks
Harold

I''ve often considered this, but it would just be directly importing  
regexes from Ruby, and the more of that I do, the more Puppet just  
looks like Ruby.

Generally, I think it''s best to make this kind of decision once --  
most of these decisions split hosts into different classes, and if  
you make that split once in the beginning of your configuration, then  
you can reuse the information throughout.

E.g., you could have network names and have a server-side function to  
pick ''net1'' or ''net2'' or whatever.
