-// FIXME: types do not hoist, but they *do* get allocated on to the global object 
-// when defined at package scope. This is inconsistent and weird: it means that 
-// we have to move EnumerableId out here to have Object.es *statically* see the
-// type, even though if we wait until we've actually executed this file, we will
-// wind up with an EnumerableId type property stuck on global, visible to Object
