Adding it as it is results in compiler error:
	./quick.d(30): Error: function quick.Test2.toString () is not c	
allable using argument types () const
	./quick.d(30): Error: expected 2 function arguments, not 0
	./quick.d(30): Error: cannot implicitly convert expression 
(this.toString()) of type void to const(char)[]

Removing const from begging allows it to compile. But it doesn't change 
anything. Still "nothing" appears ;-)
