Thank you all for your replies.

@ Timon, I have two questions:
1) How come you can omit parentheses for uniform's parameter, shouldn't it be
 uniform!("[]")(...) ?
2) Does auto chunk = new ubyte[1024]; ALWAYS create a dynamic array with
changeable length?
That is a silly question but the syntax confuses me.
