Description of Changes
This is one of the branches I had for a while, but never submitted as a PR as it wasn't a priority. Still might be nice to have eventually.
Benchmark comparisons:
That is, the difference is fairly marginal in microbenchmarks, but really shines in integration ones which are arguably more representative of real-world scenarios.
In those, the speedup ranges from 1.5x to 2.1x.
API and ABI breaking changes
If this is an API or ABI breaking change, please apply the
corresponding GitHub label.
Expected complexity level and risk
1
How complicated do you think these changes are? Grade on a scale from 1 to 5,
where 1 is a trivial change, and 5 is a deep-reaching and complex change.
This complexity rating applies not only to the complexity apparent in the diff,
but also to its interactions with existing and future code.
If you answered more than a 2, explain what is complex about the PR,
and what other components it interacts with in potentially concerning ways.
Testing
Describe any testing you've done, and any testing you'd like your reviewers to do,
so that you're confident that all the changes work as expected!
