Because nobody knows what $" is

Anyone who doesn't know what $" is, almost certainly won't understand @array[2,4], so you better make that:

my $output = join '', $array[2], $array[4];

But then, even if they know about the function join(), they probably won't understand the statement join, so you'd better make that:

my $output = join( '', $array[2], $array[4] );

Then, of course, for consistency you should make that last line:

print( "$output\n" );

But WFT!? Variable names inside quoted strings? That can't be right:

print( $output . "\n" );

But what the hell is that dot doing there!?

print( join( '', $output, "\n" ) );

But hang on a minute! Nested function calls!? We can sort that abomination out:

my $output2 = join( '', $output, "\n" ); print( $output2 );
my @array = ( 'abc', 'def', 'ghi', 'jkl', 'mno', 'pqr', 'stu', 'vwx', 'yz ' ); my $output = join( '', $array[2], $array[4] ); my $output2 = join( '', $output, "\n" ); print( $output2 );

But, but, but, where are the classes and objects and methods and, and and ... Sod this! I'm going back to a proper language like JavaPy++ Cscript 3000 where fings are dun proply!
