Subject: Regex in Ruby question

Another newbie question:

I've just started learning about regex "officially" (reading the
O'reilly book) and was trying out some of the examples (porting them to
Ruby from Perl). From what I can tell, Ruby's regex engine doesn't
support "lookbehind", and as I had only a smattering of knowledge about
regex before and no prior experience with lookaround, I was curious if
this was significant.

i.e. is there any problem that can't be solved without lookbehind?

(Note that I am not facing such a problem; I'm just curious if
lookbehind is just an optional feature that makes certain problems
easier, as opposed to being an essential thing.)

Thanks!
