This are some strange methods where I have no Idea how they relate to the JSON package in the first place o.O

Hi Chris,
I find the implementation rather unusual (e.g. the way #inject:into: is used there) and a bit too complicated (many assumptions about what returns what). #path:do: does not work correctly on its own as it relies on the argument block's return value. E.g.:
#((1)) path: #(1 1) do: [ :path :node | ] "=> DNU"
There's also some unexpected behavior:
#('foo') atPath: #(1 1) "=> $f"
I'm not sure these should be available for all collections considering all those assumptions in the method comments. Perhaps a custom class or the class side of Json would be a better place.
Best, Levente
