JSON serialization

  Hello,

I'm pondering what way to use to serialize my Moose classes to JSON. 
I've have been looking to MooseX::Storage but it seems it cannot handle 
more than basic attribute types. Just the very first class I tried: 
"Cannot handle type constraint (MooseX::Types::URI::Uri)"
There seems to be a way to add custom handlers, but the documentation is 
scarce.
I also tried the MooseX::Storage::Format::JSONpm, but the result is the 
same.

Or should I go with plain JSON module and add the TO_JSON method to my 
classes?

Thank you,
Jiri
