Given that the article was a response to criticism of a previous proposal of mine on grounds that it used exceptions for control flow, and given that I linked to that discussion (on the page for the proposal in question) in the opening paragraphs of this one I probably felt that the reasons for using exceptions for control had been adequately covered at that point.

But I was probably not trying to suggest you should regularly do this (certainly I wouldn't suggest that now), only that if you find you have a good reason to do it you shouldn't be afraid of it.
