This is expected to speed up JSON handling. Some preliminary benchmarking of the decoding function indicates speed improvements starting at modest 30-40%, and sometimes much higher -- tenfold or more. I'm not sure how this will fare in the real-life handling of JSON objects, so I'd welcome speed measurements of the current master branch as compared to previous versions (yesterday and older) in real-life scenarios, in particular in LSP and Eglot. Please report the results here, and if there are some significantly adverse effects of these changes, please report them as bugs. TIA
