+\r
+Ah, good point. I don't think this is so necessary for the other\r
+functions, but this one is weird because it requires the caller to\r
+begin the map (every other function simply emits a value, so it\r
+doesn't depend on the caller's context).\r

+\r
+Done, and it is nicer. (Apparently I had the 'date' assignment both\r
+here and below!)\r
