How to treat this?

I have the impression this might be a dumb question but…

What role does "this" play in amber? And how can I access it? I'm trying to parse a JSON string and use the

JSON.parse( string, reviver)

So I can do

JSON parse: '{ "a" : { "b" : "c" }}' with: [ :key :value |

Transcript show: '* '; show: key; show: ' -> '; show: value; cr ]

The parse is a depth-first traversal and the current object that is parsed seems to be accessible via "this". So I would need acess to it in order to be able to nest properly.

Re: How to treat this?

Accessing 'this' in blocks is done via currySelf message sent to a block to transform it so it gets this as the first parameter. Inside method, of course self is 'this'.
