Propose a merge of the abstract rewriting system subsection from rewriting into this article. That section, and this article, appear to be very nearly cut-n-paste's of one another, but also seem to be diverging in terms of quality of content, number of references, etc. Maintaining two copies of the same treatment just seems like a waste of resources (and makes the reading of thee two articles tedious, due to the repetition). linas (talk) 15:29, 21 February 2011 (UTC)[reply]
