  +You can use L<Number::Format> to separate places in a number.
  +It handles locale information for those of you who want to insert
  +full stops instead (or anything else that they want to use,
  +really).

   This subroutine will add commas to your number:

  -Normally perl ignores trailing blanks in filenames, and interprets
  -certain leading characters (or a trailing "|") to mean something
  -special.

  -The three argument form of open() lets you specify the mode
  -separately from the filename.  The open() function treats
  -special mode characters and whitespace in the filename as
  -literals
  +(contributed by Brian McCauley)
   
  +The special two argument form of Perl's open() function ignores
  +trailing blanks in filenames and infers the mode from certain leading
  +characters (or a trailing "|"). In older versions of Perl this was the
  +only version of open() and so it is prevalent in old code and books.
  +
  +Unless you have a particular reason to use the two argument form you
  +should use the three argument form of open() which does not treat any
  +charcters in the filename as special.

   	open FILE, "<", "  file  ";  # filename is "   file   "
   	open FILE, ">", ">file";     # filename is ">file"
   
  -It may be a lot clearer to use sysopen(), though:
  -
  -    use Fcntl;
  -    $badpath = "<<<something really wicked   ";
  -    sysopen (FH, $badpath, O_WRONLY | O_CREAT | O_TRUNC)
  -	or die "can't open $badpath: $!";
