Cooool!

I think it would be made even better if auto declarations and initialization of
stack variables with array literals can be combinedly used.
Currently, the following program fails to compile:

void main() { auto a = [1,2,3]; }
>> test.d(1): Error: cannot infer type from initializer
>> test.d(1): cannot implicitly convert expression ([1,2,3]) of type int[3] to int
