Well this just complicates issues. For example you can create a mutable array of vectors which uses the same methods as NSMutableArray. Now I can take that object and treat it like any NSMutableArray object. I don't even have to cast the object type.

Now mentally I know I'm editing a vector set, but the code doesn't have to refer to a GRASSVectorSetMutableArray or whatever, just a generic object or an NSMutableArray.

Now does that make my code derived work?

The GPL may be stricter, but it's also more vague. At least with the LGPL I know that linking is legal, with the GPL I don't have a clue what's legal.
