I think that was a good choice. There are many utility functions one may want to build on top of ES5's set of primitives. For example, traits.js was my attempt at providing a minimal number of utilities to treat property descriptor maps as composable traits. (The above inspect function is exactly traits.js's Object.getOwnProperties which lifts an object literal into a property descriptor map, cf. < http://soft.vub.ac.be/~tvcutsem/traitsjs/api.html>) Cheers, Tom
