False warning of Not used forward declaration

[drodil]

When using forward declaration and templates the cppclean gives false warning. Not sure if this is related to the using keyword or the use of template. To reproduce:

template<typename T>
class Container {
}

class Item;
using ItemContainer = Container<Item>;

I have the same issue with this code in header file :

class MyFwdDeclClass;

bool myFunc(std::vector<MyFwdDeclClass>& vec);

Same issue again when the usage is followed by & :

bool myFunc(MyFwdDeclClass& class);
