Append in D dynamic arrays is awful, it's slow and requires complex code (and currently there are not explanations about how it works in the D docs, see http://d.puremagic.com/issues/show_bug.cgi?id=4091 ), so it's not a good example to be copied :-) It's not fast enough for most situations, that's why there is the need of an Appender still.
