Is it possible to have a loop in config?

[Casey Rayman]

I'm using nginx as a reverse proxy and so I've got several sites which  
use exactly the same config with the exception of the port.  Is there  
a way to do something like....

array {10,20,99}

for each i in array {
	server {
		listen $i;
		...
	}
}

Perhaps an odd question, but nginx has all kinds of useful features  
I'd never thought of before.
