You can't compare them.

Objective C is very different from D. There is a language called Objective C++,
which is just a mix of C++ and Objective C. This is possible and usefull as
Objective C's class system is so different from that of C++.

You don'thave things like the message eating nil, or any that dynamic thing in
D.

"message eating nil"

that sounds like something you wouldn't want to meet in a dark alley.

something i wondered - is objective C a true extension to the compiler or is
it just a fancy preprocessor?  i wonder because the syntax is so weird, and
it would make sense if it were weird for easy preprocessing.

Well, nil is something like null. But if you call a message on it, the result is
just nil rather than an exception. So you don't need stuff like the null object
pattern.

I'm not sure. Perhaps at first it was just a preprocessor. The first C++
compilers just compiled to C, too.
