 Non-goals:
 
-* Using more than one core.
 * Be efficient while using zillions of goroutines. However, good goroutine support is certainly a goal.
 * Be as fast as `gc`. However, LLVM will probably be better at optimizing certain things so TinyGo might actually turn out to be faster for number crunching.
 * Be able to compile every Go program out there.
