Some boost headers use Objective-C keywords

I am using boost 1.49.0. An example of this is boost\local.hpp" which includes "boost\locale\message.hpp" which defines "id" (an Objective-C keyword) as a local variable in one of its inline functions. This causes an issue when boost headers are included in any code that is parsed by the Objective-C compiler and makes it impossible to include some boost headers directly in Objective-C source files. Would be nice if you could avoid using Objective-C keywords in all public headers. Albert

I'm not sure Objective-C++ compatibility should rate very high on the guideline priority list.

Standard C++ library requires all std::locale facets to have a static member called "id" of type std::locale::id which defines this particular facet uniquly. If "id" is a keyword than Objective C++ can't use std::locale object and its services + it can't use all iostream library. So this "requirement" can't be filled.

I believe you need to do something like this: http://lists.apple.com/archives/objc-language/2004/Dec/msg00060.html
