    IMHO, matrix operations are one of the most confusing and cumbersome
aspects of Cocoa.  Every time I use them, I end up trying most combinations
until I get the desired result.  C++ doesn't have this problem.  You can
simply write the matrix equations and be done with it. I love Objective C,
but operator overloading (and ctors/dtors) are the things I miss most.
Multiple inheritance -- not so much.
