 Because nil is a legitimate object in Ruby, but not in objective-c, it can
 introduce subtle bugs:

 Example:

 {{{

 framework 'Cocoa'
 array = NSArray.alloc.initWithObjects(nil,1,2,3)
 p array.size
 p array.inspect

 }}}

 Since reading the va_list stops when it finds the first nil, the array is
 never initialized with the numbers.

 I'm not sure how common this will be in practice though...
