Florian Albrechtskirchinger 700b95f447 Make iterator operator++/--(int) equality-preserving (#3332) ... Commit f28fc22 introduced const qualifiers on post-(inc-/dec-)rement operators of iterators. These qualifiers prevent the use of basic_json in place of std::ranges::range, which requires the post-increment operator to be equality-preserving. These changes appear to be the result of ICC compiler suggestions, and no further explanation is discernible from the PR discussion (#858). Further testing revealed, that clang-tidy also suggests adding const to prevent "accidental mutation of a temporary object". As an alternative, this commit partially reverts f28fc22, removing all added const qualifiers from return types and adds lvalue reference qualifiers to the operator member functions instead. Unit tests ensure the operators remain equality-preserving and accidental mutation of temporaries following post-(inc-/dec-)rement is prohibited. Fixes #3331.		2022-03-08 10:10:50 +01:00
