While I agree I believe this comment by _delirium sums this up rather well, http://news.ycombinator.com/item?id=1486502 http://news.ycombinator.com/item?id=14

  I agree more with philh's response that there is no alternative term for the true meaning of "regular expression" — a regular language, as suggested by _delirium, is not the same thing. I suppose I could accept "regex" as not being a regular expression as such, but the two are used so interchangeably that maintaining a distinction isn't very realistic. I'd personally rather a regular expression described a regular language, and "PCRE" (or so) used for the Turing-complete expressions with a similar syntax.
