      - I removed all correction logic, only error() messages are thrown on unsupported platforms
      - so the default is extern constants and if user defines extern/inline constants explicitly and the platform doesn't support it error() is thrown, the reason for this was code simplification because everything was fixed and works on latest compilers 🎉
    - after a few compiler releases I will also remove the error messages to further simplify the code
