The author of the code is the one who added that word to the code in the first place. You'd think he might remember that, even if the wording of the complaint was off.
If he does not, that invites the question of how many similar error messages are there in the code. Note that this is something that actually gets printed to stdout - in other words, if there's a bug in your app (or EFL, for that matter), your end user might see that message. I would dare say that's a pretty big WTF.
