Is there any possible way of equating file handles?

My program takes in any number of files including a '-' or none which would then read from STDIN. The problem is, i'm doing something like so: 

foreach $file (@files) {
   if ((!open (FILE, "<file")) && ($file ne '-'))
   {
        #print error and die
   }
   else 
   {
      while ($line = <FILE>) #OR if FILE is undefined then <STDIN> {
           #do something
        }
   }
}

I'd like to be able to just make FILE equal STDIN before so i don't have to fiddle around with anything in the condition of the loop. (Unless it happens to be really nice and simple to do it in the condition).
