Anyone against it?<br>
<br>
It would allow us to use std::optional which would allow us to change things like<br>
<br>
std::unique_ptr<GooString> readMetadata();<br>
<br>
to <br>
<br>
std::optional<std::string> readMetadata();<br>
<br>
where you can differentiate between "no metadata" and "empty metadata" without having to use a pointer.<br>
<br>
Seems better API to me.<br>
<br>
All the things in the gitlab CI built fine and I don't think the mac/windows builders would be a problem to get the increased C++ standard.<br>
<br>
Cheers,<br>
