If you can use Ruby 1.9, you simly can express it using 'negative look
behind':


irb(main):001:0> "test,,\\,test".scan(/(?<!\\),/)
=> [",", ","]
irb(main):002:0> "test,,\\,test,test2,\\,test3".scan(/(?<!\\),/)
=> [",", ",", ",", ","]

I never watched Grey and she was mostly background in 24 however did
you ever see her in "Third Watch?" She was yummy and in charge back
then.

I neither like her, or particularly dislike her.

I will say this, though - this does it make it slightly *less* likely
that I will sample this, when I was already leaning in the direction of
not sampling it.

She seems to have a long resum? of shows I haven't watch or studiously
avoided. The only things I'd have seen her in are an episode of Law &
Order and Night at the Museum ...

I predict her appearance will be when the show jumps the snark.

(No, that's not a typo.)

I've grown out of that phase. I didn't watch most of "The Event" for the
same reason - I have too high a "bullshit" detector for 'storyarced'
Speculative Fiction now. "Flash Forward" was the last one of those that
I'm going to sit through despite its idiocy. Those days are over for me.

Perfect SF series, or Bust!!

In all fairness, Revolution is a lot more fun to bash. The stupidity
comes so fast and so often.
