With the pipe-syntax of shells ( sh, bash, ...) this five lines could be
written as:

     "Hello World, Piped" | writeln;
     args | CmdLin | {argnum, suffix, " arg: ", argv} | writeln;

You could have a look at the pipe template in std.functional. But in 
general, I agree; a sort of piping operator would be very useful in 
algorithmic code. I find myself using the "|>" operator often in F#.
