Pretty straight-forward: template <class T> void foo() {} //compiles template <struct T> void goo()

classis only a keyword to indicate thatTis a type. It does not actually meanTmust be a class. (e.g. you can callfoo<int>().)The
classkeyword was used becausetypenamedidn’t exist when the template feature was added. See Templates in c++,typename and class.
