We still keep the error check in the function, but hide it in an outlined function inside a .cpp file, to promote inlining of the retrieval part. In the future, we should explore two things 1) Skipping over the context retrieval here, allowing direct access. I currently do not see a way to do this while keeping the "greppability" of mutable vs immutable accesses that is there now, but it would help a lot when inlining is not enabled. 2) Removing the error check, to make the function trivially inlinable, and without branches. **runtime difference** | --------- | Debug | Release | |:----------|------:|--------:| | Slow path | 0.98 | 1.07 | | Fast path | 1.04 | 1.08 | We lost bit of performance on the assertion slow path in debug mode, but together with the previous commit, it comes out at net zero. For other combinations, we see 5-10% perf improvement across the two commits.
