It evolved out of D's member function call syntax for arrays - basically, for years before we had UFCS in D, we had UFCS for arrays. However, when and how that was added to arrays, I don't know. I don't recall it ever not being in the language, but I never used D1, and I don't know if it had it. At minimum, it's been in D since early D2, if not much earlier. I'd have to do a lot of spelunking through old releases to figure out when it was added. Certainly, the origins of UFCS in D do not come from making it possible to extend user-defined types with member functions. It comes from wanting member function call syntax when using arrays (probably aimed primarily at strings, but I don't know). It's just that later it was proposed to extend it so that it would work with any type and thus make the member function call syntax universal. - Jonathan M Davis
