auto foo()
{
   if (1)
   {
       return [0, 0];
   }
   else
   {
       size_t one;
       size_t two;

       return [one, two];
   }
}

void main(){ }

Error: mismatched function return type inference of uint[] and int[]

A sufficiently smart compiler could figure out a common type for the two
arrays. :)
