C++17 `inline variables` are far more convenient compared with
extern const variables declarations, and in general are more ODR-safe and
memory efficient compared with non-inline const variables definitions.
It is a part of a number of code styles to use C++17 `inline variables`.
The checker would help users to follow this code style.
