In fact, the current example (which is not the greatest of all) 
is essentially a one/two-liner, something along the lines of:

     auto lines = stdin.byLine.map!(line => line.length);
     writefln("Average line length: %.4f.", 1.0 * lines.sum / 
lines.array.length);

Ofc this is not the greatest piece of code ever and it's not 
lazy, but at the very least it showcases an auto declaration, a 
lambda, a formatted print, a template invocation and UFCS syntax, 
you get the point... oh wait, that and a lack of a "mean" 
function in the standard library...

I bet you will come up with much better ideas!
