Sounds like this idea is limited to the curl tool and wouldn't add anything to libcurl, which is great. I'd prefer libcurl leaving JSON to other libraries. I use bash variables inside JSON with curl all the time, which leads to string escape screw ups. I know there are alternatives that make testing REST + JSON easier, but since our software uses libcurl in production I prefer to test with curl to keep things consistent.
