Why? How can a delegate which returns nothing be used as an
array which is going to be printed on the screen?
You pass the string to the delegate, which does whatever with
it somewhere else.
So you call: `passed_delegate("your string");` and it can
forward it to writeln or whatever.
But how does it forward it if it's:
void delegate(const(char)[]) sink // ?
It returns nothing, and just takes an array of characters as a
parameter.. Just how does it print?..
