But you *could* write nice little programs like:

main.mm:

 #include <iostream>
 #import <Cocoa/Cocoa.h>
 using namespace std;
 int main()
 {
 NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
 NSString *aString = [NSString stringWithString: "Hello, World!"];
 cout << [aString cString] << endl;
 [pool release];
 return 0;
 }



Operative keyword here being "can", not "want" :-)

PS. There even seems to be a D project:
     http://www.dsource.org/projects/docoa/
     How about "Objective-D", anyone ? :-)

That's horrendous.  :)

Has Apple ever chosen the "right" language? Pascal... Object Pascal... 
Objective-C... maybe they are finally starting to come around. oh well :-P
I just wish Dylan had worked out. Imagine a mainstream system API entirely 
in lisp - yikes.

Not really, just that market forces made them support C++ and Java.
The "preferred" language for all of NeXTStep is still Objective-C...


(there's also the procedural API, Carbon, but that is Pascal-inspired
C - not* C++, and there are of course the Java 1.4 JVM libraries too)

* Unless you count the MacApp class library as a "system" library ?
   http://developer.apple.com/tools/macapp/ (no longer supported)


Compared to ugly C++, Objective-C(++) is not that bad. But D is better
Mac OS X also runs that Java clone by that other Monopoly company. ;-)
