Yes, in a way.
Spirit only requires forward iterators, not bidi ones, like xpressive. Input
iterators can be adapted to become forward ones in a fairly straightforward
way, and indeed, spirit has a customizable multi_pass iterator adapter to do
just that.

Up until now I thought spirit to be an overkill for my stuff, but I'm
considering using it now.
