    Description

      It is impossible to find something in `QHash<QString, Something>` without memory allocation, if input data has type `QStringView`.

      It would be nice something like http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0919r2.html (part of C++2a) would be implemented for `QHash`.
