<pre>template<class T>
class X {
T f(T x) { return x; }
T foo(void);
};
template<class T>
T X::foo(void)
{
return f(5);
}
For the code above clang emits the following diagnostic:
% ./clang template.cpp -o template -Wall
template.cpp:14:3: error: 'X' is not a class, namespace, or enumeration
T X::foo(void)
^
template.cpp:2:7: note: 'X' declared here
class X {
^
1 error generated.
But X is actually a class, so the error is a little bit misleading.</pre>
