I've been messing around with something similar to this and I can't figure out why it won't work. 
sub x{
  local(*A)=$_[0];
  if(opendir(R,"/usr")){x(*R);
  }
}

and when I try to do something like: 
sub x{
  local(*A)=$_[0];
  if (opendir(R,"/usr")){while(<R>){print;}
  }
}

I get: 
[s0ttle@ween]%perl subtest
Read on closed filehandle <C> at a line 23.
[s0ttle@ween]%fuq
