- `fun` was used for variable/field names in a number of places. These have been replaced by similar or more descriptive names, to avoid name shadowing, which is not allowed in the GCC-based build. - Use in-place construction instead of assignment. - `FilteringSourceAccessor::checkAccess` had a fallback for when `makeNotAllowedError` was null. Since `MakeNotAllowedError` is now `fun<>`, we've proven the null branch is dead code and have removed it. - `src/nix/flake.cc`, `src/nix/search.cc`, `src/nix/ls.cc` are left as-is — the self-referential lambdas there cause too much reindentation for too little benefit.
