Ha! :) Maybe there's something you might want to do with the intermediate syntax objects in some cases? Properties maybe? I'm not sure. Looks like it's been that way for more than 5 years now, tho, so it seems unwise to change it. Unless someone knows why it is a bad idea, how about adding a #:all? argument that flattens all the way down? I don't see many uses of flatten-begin in our tree, but the one in compatibility/package sure looks like it could use the #:all? argument. Ditto the one in TR (in class-prims.rkt). And I'm pretty sure that replacing the hand-rolled loops in drracket for doing this (they predate that library) would use the #:all? argument if they were rewritten.
