Moved this to the proper forum from this thread.
Issues in AHK v1:
- all numbers are unquoted on dump, even if src data was quoted
- numbers that start with zero are always quoted
- empty arrays are detected as maps (how to detect obj type in AHK v1?)
this shouldn't be an issue since you can add a ["key"] to a linear array, or populate an object with numerical keys in AHK v1
