This is a comment based on nothing.
For instance, -fobjc-arc-exceptions slow down only the exception throwing because it properly handle the stack unwiding, and it does not slow it down more than enabling exception in any C++ code.

Obj-C++ is a first class language in clang.

>> <soapbox>I recommend avoiding Objective-C++ as much as possible. It's slow to compile, bloated to run (particularly with ARC since it turns on -fobjc-arc-exceptions), buggy in the compiler and the debugger, and mostly a mess in my experience giving the worst of both worlds. C++ is fine. Objective-C is fine. Just keep the interface between them as small as possible. </soapbox>
