Refactoring with C++17 std::optional
Or nonstd::expected. Personally, I would rather use output parameters and an enum result or a std::variant over std::optional, because at the very least you have the option for more specific error diagnostics.

std::expected (with monadic interface) implementation in C++20 (P0323, P2505)
As someone who is new to this API (so I can't discern from the list of features which might be better for my use case), I second the question, and I'd like to extend the question to how it compares to https://github.com/martinmoene/expected-lite and https://github.com/bitwizeshift/result as well.
