	 * Further TODOs for compilation:
	 *
	 * - OpMinus with a single literal operand could be treated as a negative literal. Will save a
	 *   pointless loading of 0 and then a subtract instruction in code gen.
	 * - allow other accessors/resolvers to participate in compilation and create their own code
	 * - A TypeReference followed by (what ends up as) a static method invocation can really skip
	 *   code gen for the TypeReference since once that is used to locate the method it is not
	 *   used again.
	 * - The opEq implementation is quite basic. It will compare numbers of the same type (allowing
	 *   them to be their boxed or unboxed variants) or compare object references. It does not
	 *   compile expressions where numbers are of different types or when objects implement
	 *   Comparable.
