jq hasn't had much work done to make it fast though.

There's two classes of performance problems:

- implementation issues

- language issues

The latter is mainly a problem in `foreach` and also some missing ways to help programmers release references (via `$bindings`) that they no longer need.

The former is mostly a matter of doing a variety of bytecode interpreter improvements, and maybe doing more inlining, and maybe finding creative ways to reduce the number of branches.
