Merge? 

I'm sorry about the deletions that I made last August (referred to above—my username is Skal). I would take it upon myself to fix the damage I've done to what was otherwise a reasonably good article, were it not for the fact that this article is probably superfluous. I see little in this article (even as it was before I mutilated it) that is not there in the article on Phrase structure grammar (which redirects to Chomsky hierarchy). Even what little is (or was) here that is not there rightly belongs to that page. Therefore, I suggest that this page be merged with Phrase structure grammar. Any thoughts?

By the way, should Phrase structure grammar redirect to Chomsky hierarchy? It's been a while since I last read a book on syntax, but it may be useful to have a separate article detailing each of the concepts, as I believe that phrase structure grammar and Chomsky hierarchy are not the same thing.
