Robin- That was something I definitely considered very hard in the beginning. But, by the way ActionView works with render() being called recursively, it means that searching for these fields would have to take an aweful lot of processor power to accomplish. You'd have to scan the entire document at least 1-3 times on any render on any page. Also, *most* pages don't have <textarea> or <pre> tags. But, if they do, I wanted to make it easy to support.
So, we chose not to do that because of the significant application slowdown that would be required. ~ is not a perfect solution, but its my favorite so far. In fact, the only downside is someone has to look into the API to find it. If you want to scan your entire document, just add "~ yield" where "= yield" is in your application layout file. Those are my thoughts. Thoughts from the community? -hampton.
