Of course you can "mix the code", that's the whole point. You can't mix the
_features_. ObjC objects can't be templates, you can't send them to iostreams,
they have to have "C" linkage, you can't throw an exception from C++ and catch
it in ObjC or vice versa, ObjC objects can't interact with operator
overloading, and so on. An Objective-C++ compiler is a normal C++ compiler
with the syntax and runtime additions from Objective-C. It works because all
of the additional syntax is illegal C++ (just as with C). :)
