     * int (= int32)
     * uint (= uint32)
     * float (= float64)
     * decimal
     * number (= decimal, change with -number: option)
     * dynamic
   * Explicit Sizes
     * int8, int16, int32, int64
     * uint8, uint16, uint32, uint64
   * PrimitiveTypeMembers
 * Complex Types
   * Class
     * Single inheritance
     * Heap-based
   * Struct
     * No inheritance (other than Object)

     * No code implementation
 * Nilable Type
   * foo? - can be "foo" or "nil"
   * applies to all types
