And you're always going to get all those args in the right order? I know I wouldn't.

# round em up...
my $args = { # no need to worry about the order
  arg1 => $some_variable, 
  arg2 => $some_other_variable, 
  arg3 => $and_yet_another_variable, 
  arg4 => $and_one_more_for,
  arg5 => $luck,
  arg6 => some_other_function(),
  arg7 => $maybe_a_variable or $default,
};

# ...and herd em in
my $some_return_value = some_function($args);

if($some_return_value) {
    # do some stuff here with some_return_value 
    # and if there are more than a few lines
    # I'd consider another sub
} 
else { # and don't cuddle your else
   # report or otherwise handle the error 
   # in another sub :-)
}

sub some_function {
  my ($args) = @_;
  # no need to worry about the order here either
}

I should point out I'm presently having terrible trouble debugging an app (that I'm writing). It gets more vertical by the day! :-)
