when opening an objective-c header in a mixed c+/objc codebase, it is typically opened in a c+ parse context, showing lots of warnings when using objectiv-c in the header. i wonder if the quality of life could be improved.

compare attached project:

• foo.h is included by foo.mm
• bar.h is included by main.cpp

both foo.h and bar.h list both CXX and OBJCXX contexts, but default to CXX. i wonder if it is possible to improve the quality of life by detecting the contexts where the files are included in. e.g. if a header is included in any OBJCXX source file, it could have a default parse context of OBJCXX. or alternatively maybe: if there is a parse error in the CXX context and the target has an OBJCXX context, it could switch to OBJCXX. not sure if there are any fundamental problems with this kind of heuristics, though
