It seems like a huge waste of time to create a new language so that people will not do "stupid" things in their templates. The case of PHP is especially amusing. How about using common sense? I mean if a programmer intends to do "dangerous misuses" in the templates, maybe he shouldn't work on it in the first place. Having a person not being able to tell whether something is dangerous or not, working on the project and then creating a template language to forgive the lack of knowledge is just asking for trouble in the long run.
