I'm kind of surprised that there has been no mention of UnQL on this mailing list, especially since the creator of couch was one of the two "inventors". Also UnQL adoption would obviously have a big impact on CouchDB.
I'll throw out my 2 bits, fwiw ... I haven't got any good arguments yet, but I feel having a text-based SQL-like language for couch would be a big step backwards. I do feel couch needs to expand it's query capabilities, and I trust it will. But I would imagine the solution to be more modern than the old process of building up a query text string and sending it off. Maybe it is just an emotional reaction after all the years of hating the impedance mismatch of the SQL language and all the languages I had to use it in.
