Duck typing, must it be dynamic?

Question

Wikipedia used to say* about duck-typing:

In computer programming with object-oriented programming languages, duck typing is a style of dynamic

Answer 1

C++ and D templates are a perfect example of duck typing that is not dynamic. It is definitely:

typing in which an object's current set of methods and properties determines the valid semantics, rather than its inheritance from a particular class or implementation of a specific interface.

You don't explicitly specify an interface that your type must inherit from to instantiate the template. It just needs to have all the features that are used inside the template definition. However, everything gets resolved at compile time, and compiled down to raw, inscrutable hexadecimal numbers. I call this "compile time duck typing". I've written entire libraries from this mindset that implicit template instantiation is compile time duck typing and think it's one of the most under-appreciated features out there.
