The changes themself in terms of functionality look OK to me - but I want someone else with deeper understanding of the context to take a look before this gets merged.

In terms of style, here are some of the categories of minor issues:
- unneeded includes
- wrong case for variables (need `PascalCase`, the surrounding code also uses that, so no need for not following the global convention https://llvm.org/docs/CodingStandards.html#name-types-functions-variables-and-enumerators-properly)
- missing `const` qualifiers and `auto` -> `auto *`
