Just a quick aside from someone who merely lurks on this list: in SQL, it's quite possible to use keywords in a fashion similar to that desired by the inquirer, and it's actually possible to double-quote keywords and use them as names for things. I'm not advocating more complicated parsing technology for any Python implementation, but I think it's pertinent to point out that the technology isn't particularly obscure.
