Ah, I thought you meant that the class was deprecated in 10.6
Glad to hear it isn't.

Yes, being careful to wrap integers in NSInteger objects lists you keep them in 
dictionaries.

That's a shame I was hoping we would be able to get gnustep-make to 
cross-compile testcases for iOS, and then execute them inside the iPhone 
emulator, so that we could easily verify the actual behavior of classes in the  
Apple iOS implementation in the same way that we can for Foundation classes in 
OSX.
