We don't even need templates for JSON output; there's a Perl module
(called JSON, unsurprisingly) that turns a Perl object directly into JSON.

Hm, that's not really what I meant by JSON output.  That's RDF output
wearing different clothes.  What I was thinking of was something along
these lines:

{
  "name" : "Red Lion and Sun, N6 4BE",
  "uri" : "http://london.randomness.org.uk/wiki.cgi?id=Red_Lion_And_Sun,_N6_4BE;format=json"
  "wgs84_lat" : 51.572545,
  "wgs84_long" : -0.148517,
  "locales" : [ "Highgate", "N6" ],
  "categories" : [ "Pubs", "Pub Food", "Beer Gardens" ],
}

Something that can trivially be turned back into an object without the
need to parse RDF and work out what all the triples represent.

Or even:

{
  "name" : "Red Lion and Sun, N6 4BE",
  "uri" : "http://london.randomness.org.uk/wiki.cgi?id=Red_Lion_And_Sun,_N6_4BE;format=json"
  "wgs84_lat" : 51.572545,
  "wgs84_long" : -0.148517,
  "locales" : [ "Highgate", "N6" ],
  "categories" : [ "Pubs", "Pub Food", "Beer Gardens" ],
  "nearby" : [
               {
                 "distance" : 153,
                 "uri" : "http://london.randomness.org.uk/wiki.cgi?id=Wrestlers,_N6_4AA;format=json"
               },
               {
                 "distance" : 311,
                 "uri" : "http://london.randomness.org.uk/wiki.cgi?id=Flask,_N6_6BU;format=json"
               },
               {
                 "distance" : 589,
                 "uri" : "http://london.randomness.org.uk/wiki.cgi?id=Highgate_Station;format=json"
               }
             ]
}
