After I was talked into my senses at the IRC channel, I decided to drop the
enforced-theme-spec-file. Then I began to browse through the Edje api to see
where it could use a little more verbosity. Only edje_object_part_text_set()
is in the same situation.
So while having edje_object_part_swallow() (or text_set) return something is
a good idea, it does not tell the application developer what actually went
wrong. Implementing an Error system in the same manner than
edje_object_file_set seems like an overkill to me.
Thats why I think a function to check the part type is a better approach to
this problem. This way applications can be more verbose about the reasons for
failure, easing theme development.
