  consider having all the indends the same (just think about it)

  something along these lines:

my @files = sort
  map { $dir . "/$_" }
  grep { !/^\./ }
  readdir DIR;

  because when you have code like this:

my @files = sort
  map { $dir . "/$_" }
  grep { !/^\./ }
  readdir DIR;

my($firstValue, $secondOne, $andSomethingElse) = function(
  $firstParam,
  $secondParam,
  $thirdParam
);

$andHereWeGoAgain = yetAnotherFunctionWithLongNameAndLotsaParameters(
  $firstParam,
  $secondParam,
  $thirdParam
);

  it's a lot more readable then if each one would have it's own
different indent... IMO. While I hate the idea of indentation being
enforced like it is in python I think that being consistentin rules and
visuals (how it looks) is very important for readability of programs.
