No doubt this tool is lacking. However I will say that for me the most important quality in my `jq`-like is not conciseness. My main frustration is that I always forget the small details of how `jq`'s language works and spend 10 minutes googling. E.g doing operations within arrays of objects, using select, and so on. Maybe I'm just dumb, but I'm fond of tools that accommodate my dumbness!
Precisely. The first pass generated a temp file and compiled/ran it, but that lead to annoying pauses when trying to run simple scripts (probably 500ms latency? Maybe a tad more?). Yaegi cut that latency dramatically. I think you’re right that this may make it slower for larger scripts or for sufficiently large inputs, however the biggest bottleneck for me with jq isn’t performance but learning it’s language repeatedly.
