<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I disagree with the behavior here. I think that when setting an extended object field, we should not return an error if a field with the given name already exists. I think we should instead overwrite the previous value with the new one.
Why? Consider the scenario of people writing a template with common default options for a particular object. The majority of objects that use this template will just add new options on, but some might wish to override the default value on the template. (This came up in a discussion Richard and I had when I was trying to figure out how to handle duplicate items for features config)</pre>

1. Extended fields
Extended fields are fields specifically marked as extending an object. This means they are not held to the same type safety as normal fields and simply exist as a list that can be queried. The pro of this is that the object that is extended does *not* have to be modified when other modules need to attach data to it. The con of this is that type safety must be enforced at the time of consumption by the user of the extended field. A test is also provided which confirms functionality.
2. Opaque sorcery data
Previously sorcery data was placed directly in the structure definition for objects. This had the consequence of requiring any modules using the structures to be recompiled if the sorcery structure changed. The change attached adds a generic sorcery object allocation function which allocates enough room for an internal opaque structure. This has the benefits that modules do not need to be recompiled if internal details change and it also allows additional data to be attached to sorcery objects and properly deallocated when the object is destroyed.</pre>
