Robert Muir commented on LUCENE-152:
------------------------------------
Ryan: maybe, I thought of this too myself looking at the patch.
Then again there are probably other kinds of refactoring improvements we could
make... honestly I didn't dig deep enough into this one to see if it can be
solved just by 'add Appendable interface to CharsRef' or to even think if thats
the right thing to do.
I don't think we should move it out of the analysis package for now (maybe i
shouldn't have put it in util even in the patch) unless there's something else
that actually wants to use it: I think this would be premature.
