Yeah, I think it would be neat if the library could support self-referential many-to-many in a nice way.

I'm not sure about the left_name/right_name design though. Would it be possible to have this work as the user intends, by spotting that the other table name "people" matches the name of the current table?

python db["people"].insert({"name": "Mary"}, pk="name").m2m( "people", [{"name": "Michael"}, {"name": "Suzy"}], m2m_table="parent_child", pk="name" ) The created table could look like this: sql CREATE TABLE [parent_child] ( [people_id_1] TEXT REFERENCES [people]([name]), [people_id_2] TEXT REFERENCES [people]([name]), PRIMARY KEY ([people_id_1], [people_id_2]) ) I've not thought very hard about this, so the design I'm proposing here might not work.

Are there other reasons people might wan the left_name= and right_name= parameters? If so then I'm much happier with those.
