Note: when I said "standardized" I meant in the "de facto standard" way. Arc has plenty of those. :P
I agree that Arc has essentially no de jure standards[1], and I think that's a good thing.

* [1] The closest thing would probably be whatever pg does, but that would only concern the question of what official Arc is; other implementations would be free to either follow official Arc, or branch off into a different Arc-like dialect.
