I have a class Foo with a method -(unsigned long long)size.
I realized today that when I get an id reference to an object of
class Foo, if I don't explicitly cast to (Foo *), the result is
meaningless.
I didn't check, but it *seems* to be interpreted as signed int
Here's the code:
- (id)outlineView:(NSOutlineView *)outlineView
objectValueForTableColumn:(NSTableColumn *)tableColumn
byItem:(id)item {
//...
NSLog(@"s:%qu", [item size]);
NSLog(@"s:%qu", [(Foo *)item size]);
And the results:

2007-02-08 21:19:40.094 Singular[19919] s:6212
Why??
