An object type that contains `Json` causes a recursive error in conjunction with `Draft`/`WritableDraft` types from Immer

[mcmire]

If you have an object type such as:

{
  foo: Json
}

and you use it to change state within an Immer produce callback — such the callback that update in BaseController v2 takes — then you will get an error:

Type instantiation is excessively deep and possibly infinite

This is happening because Json is a recursive type and Draft and WritableDraft trampoline as they recurse through that Json type. There's an open bug report on the Immer issue tracker with a proposed fix that was eventually reverted.

We should work out some way to avoid this.

Some starting points for tackling the "Type instantiation is excessively deep" error:

• TypeScript feature - Tail call elimination on conditional types with accumulator strategy: https://devblogs.microsoft.com/typescript/announcing-typescript-4-5/#tailrec-conditional
• Accumulator strategy example: https://dev.to/tylim88/typescript-loop-tuple-with-length-1000-4kg
• 0 extends 1 trick for extending tail recursion limit: https://github.com/microsoft/TypeScript/issues/49459

This might not be enough to resolve the issue if the mutual recursion depth is infinite even with tail call elimination.

Might be resolved by TypeScript 5.5: https://github.com/microsoft/TypeScript/pull/57293

I checked the Immer repo and it looks like this problem still exists: https://github.com/immerjs/immer/issues/839
