You can put an expression tuple ("expression AliasSeq"??) there. T.init is

What is T in this case? I wondered, and it is an empty expression tuple
(prints out as "()"). Interesting.
Note, this doesn't seem to work on 2.067.
There are other ways to solve this too:
void foo() {return foo(null);}
void foo(T...)(string str, T args) {...}
I find it quite fascinating that in anonymous' solution, the T.init
doesn't ever actually get used!
