+The function returns a new fancy source. Calling it with no arguments reads
+the next chunk as usual: any chunks previously pushed back are returned
+first (most recently pushed back, first), and once none remain it falls
+through to <tt>source</tt>. Calling it <em>with</em> a chunk argument does
+not read anything: it pushes that chunk back onto the internal stack for a
+future no-argument call to return.
