>
> A few of the critical code paths in {{jsonify}} involve unnecessary temporary
> string construction and copies (inherited from the {{JSON::*}}). For example,
> {{strings::trim}} is used to remove trailing 0s from printing {{double}}s. We
> print {{double}}s a lot, and therefore constructing a temporary
> {{std::string}} on printing of every double is extremely costly. This ticket
> captures the work involved in avoiding them.
