What's the relationship between C++ template and duck typing?

Question

To me, C++ template used the idea of duck typing, is this right? Does it mean all generic types referenced in template class or method are duck type?

Answer 1

Yes, sort of - for example if type X has AddRef(), Release() and QueryInterface() methods with appropriate signatures it can be used as a COM object with CComPtr template class. But this is not complete duck typing - type checking is still enforced for parameters.
