Two tiny nitbits:
  1. It's a good thing to put the local in a block (so ++), but with unexperienced users (the poster) it may be nice to note what it does. Well, the {local....} BLOCK restricts the scope of local to that block. So after the block, the $/ has it's original value (the line separator). One can read more about these and other vars in perlvar.
  2. (Really tiny)The foreach was copied from the original post (and it works), but here is a for more precise. A foreach loop is used to change the contents of an array, for is not. So for reading in a file, I would recommend for. A typical use for foreach: 
    @array = 0..100;
foreach $item (@array){
  $item += 10 if $item <100;
}
print join "\n", @array; #prints the numbers 10 to 109 and 100

    You can read more about it in for vs foreach.
Hope this helps,

Update: For clarity, for and foreach *are* synonyms. It's just a matter of convention....
