Comment #2 on issue 693 by tudor.gi...(a)gmail.com: JSON import / export for Moose http://code.google.com/p/moose-technology/issues/detail?id=693 No concrete scenario. But, we have JSON support (Lukas implemented one on top of PetitParser even) and there are plenty of other systems that know how to consume and produce one. I just think that it would be nice selling point to say that we can serialize in JSON.
