Therefore, after reading the word "Extension" in three different contexts, I started wondering and various questions came to mind, starting with---Whence came UFCS?
The answer I always say back in the day for the functionality was that it was a bug for arrays. The term UFCS though is much newer and just comes from discussion for applying the array bug to all types. Who started it, why it caught on I don't know.
The use of the term Extension I believe is because of the implementation/syntax approach used to describe this behavior in C#. In C# you don't have free functions, so instead you need a new class with static methods. This makes the new class act as an "extension" of another object. D having free functions and the functionality working on more than objects means "Extension" wouldn't be a good term to describe it.
