	// error: U is not a type, no typename or class before its name
	// fix:
	template <typename T, typename U, typename V> void f1(T, U, V);

(b)

	// error: redeclaration of parameter T
	// fix:
	template <typename T> T f2(T &);
(c)
	inline template <typename T> T foo(T, unsigned int*);

	// error: inline on the wrong place
	// fix:
	template <typename T> inline T foo(T, unsigned int *);
(d)
	template <typename T> f4(T, T);

	// error: no return type
	// fix:
	template <typename T> void f4(T, T);
(e)
	typedef char Ctype;
	template <typename Ctype> Ctype f5(Ctype a);

	// legal: hides outside alias to char, Ctype is a type that will be deduced from the argument passed to f5 inside f5
