Using variables in classes definition

[paguerlais]

I need to define a variable and a class depending on that variable.
Something like :

<example>
control:
      servers = ( host1 host2 )

classes:
      i_am_a_server = ( ${servers} )
</example>
It doesn't work because :
- ${servers} must be enclosed in quotes for syntax needs
- if ${servers} is enclose in quotes, it is considered as a command+
parameters which must be executed and whose result is used to defined
i_am_a_server.

I need both the variable and the class because somewhere later in my script
I give the variable value as a parameter to an external script
(shellcommands), and some sections of the script are activated only if the
running host belongs to the list "servers".
Of course I can repeat the hosts list on the "i_am_a_server" class
definition, but each time I modify "servers" I must then think to modify
also "i_am_a_server" :-(

I couldn't find something in the docs. Does somebody has any idea ?
