The current logic in `js_to_json` tries to rewrite octal/hex numbers to decimal. However, when the logic actually happens the `"` or `'` have already been trimmed off. This causes what were originally strings, that happen to look like octal/hex numbers, to get rewritten to decimal and returned as a number rather than a string. In practive something like: ```js { "0x40": "foo", "040": "bar", } ``` would get rewritten as: ```json { 64: "foo", 32: "bar } ``` This is problematic since this isn't valid JSON as you cannot have non-string keys.master
