It's a possibility, but I'm not sure I understand the use case well
enough. In the use case you're describing, I would simply make getPath
throw if it can't produce a valid string for whatever reason.

I do use optional error info in exceptions but not like this. Example
would be boost::errinfo_file_name, which may not be present in all
read_error exceptions because some read errors do not involve files.
