Yes. I was looking to embed it in a tool, but decided against it after looking at its implementation. It parses the expression with a stack and executes it directly, and its JSON parsing is much the same. I doubt the parsing would be close to competitive with RapidJSON, let alone simd-json. The conditionals and pointer chasing of such an implementation are stumbling blocks to performance. The C code is clean enough as C code goes, but fairly monolithic. And it’s C, so it’s not noticeably slow until you start processing GB. But it would probably take a rewrite to improve its performance significantly.
