Ah, sorry, I didn't see that the code was in the original mail.

You might find it helpful to use an editor (e.g. vim) that can show mismatched
brackets. It will easily help spot this kind of error.

I know that the Apple examples all do this, but this is a really stupid idiom.
Adding the [pool drain] line to the end of main() makes sure that all of your
temporary objects are destroyed before the program exists. This is a complete
waste of CPU cycles - the OS will reclaim their memory (without needing to swap
it back in if it's been swapped out) when the process exits and you should
never rely on -dealloc/-finalize being called on an object.
You also have an error here because you create a variable called Pool then send
a message to pool (not the same - C is case sensitive). This whole thing would
be better written as:
[NSAutoreleasePool new];
NSLog(@"Programming is fun");
return 0;
