Round trip is now possible:

Round trip with RPC blocks

(getJSFromRPCStruct CloudVariables getVariable (reportUnicodeAsLetter (unicode a)) (reportUnicodeAsLetter (unicode b)))

@brollb Can you take a look at this? It's a little messy, but it seems like it's working alright.

Also, a thought, it doesn't need to be merged, these changes might make much more sense as an extension if we have no intent to reimplement native blocks this way. The use case of feeding the code into an LLM would likely be done through an extension anyways.

There is now a "Blocks to Code to Blocks" extension which includes some of this functionality (including the ability to output a full project as Lisp-y code).

Closed, if the native functionality is ported, it will be part of a larger update, for now the extension is a better way to implement it.
