I was looking through the source code for Data::Maker and noticed the author put a lot of spaces around his expressions.

sub rand_date {

    # Get the options hash
    my %options = @_;

    # use the Date::Calc module
    eval q{ use Date::Calc };

    cluck($@) && return if $@;

    my ( $min_year, $min_month, $min_day, $max_year, $max_month, $max_
+day );

    # Get today's date
    my ( $year, $month, $day ) = Date::Calc::Today();

    if ( $options{'min'} ) {
        if ( $options{'min'} eq 'now' ) {
            ( $min_year, $min_month, $min_day ) = ( $year, $month, $da
+y );
        }
        else {
            ( $min_year, $min_month, $min_day ) =
              split ( /\-/, $options{'min'} );
        }
    }
    else {
        ( $min_year, $min_month, $min_day ) = ( $year, $month, $day );
    }

    if ( $options{'max'} ) {
        if ( $options{'max'} eq 'now' ) {
            ( $max_year, $max_month, $max_day ) = ( $year, $month, $da
+y );
        }
        else {
            ( $max_year, $max_month, $max_day ) =
              split ( /\-/, $options{'max'} );
        }
    }
    else {
        ( $max_year, $max_month, $max_day ) =
          Date::Calc::Add_Delta_YMD( $min_year, $min_month, $min_day, 
+1, 0, 0 );
    }

    my $delta_days =
      Date::Calc::Delta_Days( $min_year, $min_month, $min_day, $max_ye
+ar,
        $max_month, $max_day, );

    cluck('max date is later than min date') && return if $delta_days 
+< 0;

    $delta_days = int( rand( $delta_days + 1 ) );

    ( $year, $month, $day ) =
      Date::Calc::Add_Delta_Days( $min_year, $min_month, $min_day,
        $delta_days );

    return sprintf( "%04u-%02u-%02u", $year, $month, $day );
}

I found it very clean and easy to read. I'm an Emacs user and would like to switch to that mode of formatting my text. But I'm not sure if that's possible.
