I would really not like this semantic to be changed, as it is consitent
over the language
Maybe you should rewrite as :
classes: "webserver" or => {"lax_it_web01_prod01",
"lax_it_web02_prod01" };
classes: "nagios" or => {"lax_it_web01_prod01" };
classes: "postgress" or => {"lax_it_db01_prod01" };
classes: "zenoss" or => {"lax_it_db01_prod01" };
And you could even set up classes based on regexp, like
classes: "webserver" expression => classmatch("lax_it_web.._prod..");
(I suspect that using `-` in a class is not allowed, but i'm not 100% sure)
