Hello, Cppcheck show a false positive about 'The class 'xxx' does not have a constructor although it has private member variables. [noConstructor]' style warning when using cpp 'using' keyword with same alias than the class name. A related issue was previously fixed (https://github.com/danmar/cppcheck/pull/3160), but was incomplete. You will find a PoC with details here: https://pastebin.com/4JERvmDH Thank you for the tool, Paul
