`std::function` is a heavy object. Passing it by-value requires a heap allocation. It is also opaque to the compiler such that it cannot be inlined even if `drop_file` with a lambda is inlined. I'd also worry about it require linking to lib(std)c++ library. LLVM for instance has llvm::function_ref as a more lightweight alternative. C++26 also has std::function_ref
