Is there any position on whether getOwnPropertyDescriptor should not have side-effects? I ask because some v8 getOwnPropertyDescriptor *do* have side effects (for example, Object.getOwnPropertyDescriptor(new Error, “stack”) will call Error.prepareStackTrace (it used to not)). Currently I treat getOwnPropertyDescriptor as a “safe” way to observe an object — (unlike say calling each member on an object which could set off getters).
