$dbw->replace( 'redirect', array( 'rd_from' ), $set, __METHOD__ ); $dbw->delete( 'redirect', $where, __METHOD__);These I consider wikiNeedL phrases, and they're (almost) perfect. Some helper agent is located and told about some need that ought to be fulfilled, and what is needed is expressed clearly using wiki concepts. No details about how to do it are included, except for that string 'rd_from' which seems to be a column name in some relational schema, and that would be forbidden in wikiNeedL proper.
I think you are way overthinking things in general, and failing to understand the existing code in the specific two examples above. Both contain a lot more "details about how to do it" than just the 'rd_from' column (see: 'redirect', $set, $where). It might be helpful if you took the relevant surrounding code (e.g. where $set is defined) and rewrote it in the newly proposed system so we can see exactly what you are talking about.
