 * Paul August &#9742; 18:33, Feb 6, 2005 (UTC)
 * Actually, this one needs more than a merge. Neither the WP article nor the PM article describes the arithmetical hierarchy on sets of reals, only on sets of naturals. They're pretty much the same thing from the descriptive set theoretic perspective, though not from the computability perspective. Article needs to be rewritten with the more inclusive descriptive set theory definitions, then the computability ones should be explained as consequences. --Trovatore 04:20, 6 October 2005 (UTC)
