This revision is now accepted and ready to land.

Ah, the tests fail to compile because we now have an overload where the only difference is `function_ref` vs `StringRef`.
This works fine with `std::function`, STL probably ensures the conversions from `StringRef` to `std::functtion` fail and `function_ref` will only fail at constructor instantiation time.

I'll keep this open for now, will see if it's feasible to make `function_ref` similar to `std::function` in that case.
