I don't think this'd be necessary - you'd just have to override quantize-position with a callback that sets stem-begin-position and length. The problem is that Stem::internal_stem_begin_position expects that, if there is a beam, the value of stem-begin-position will be set by Beam::set_stem_lengths and that it can recuperate this value as the result of the callback. So long as the quantize callback does this, there shouldn't be a circular dependency. I can write this on the plane tomorrow.
