Json to JsonBuffer and back 2.0.0-M1

[dpa...@gmail.com]

Hey all,

Is there an idiomatic way to take an immutable Json and convert it to a JsonBuffer and back in 2.0.0-M1?

I want to be passing around Json, but internal to some methods, I have a lot of manipulation to do, so would prefer to be working with a JsonBuffer.  I saw some old snippets for doing this in 1.1.0, etc - but haven't been able to grok how to do this on 2.x

Any tips?

Thanks!
