It should.
However, I was talking about two different rgex implementations, not two
different languages. I would make the notation the same for both.
Except: there are things that you generally can't do with a DFA, such as
capturing submatches, and repeated matches like
/(['"]).*?\1/
(--> the "\1"). I think that's about it.
And the DFA would only be used for input line terminator scans. No user
choice.
