[clang-format] incorrectly interprets C++ file as Objective-C

[uleysky]

Minimal example test.h:

[this,a=a]() -> struct S { return {}; }

.clang-format:

---                                                                                                                                                                                                                                                                           
Language:        Cpp

Output of clang-format --style=file test.h:
Configuration file(s) do(es) not support Objective-C: /tmp/.clang-format

clang-format --version:
clang-format version 18.1.7

My gut feeling is that this is a bug in the annotator in that it thinks the ] after the a=a is a ObjCMethodExpr

Seems to work, thanks!
