rymiel added inline comments.


================
Comment at: clang/lib/Format/TokenAnnotator.cpp:319
+           Prev->Previous->isOneOf(tok::period, tok::arrow)) ||
+          (!Line.MustBeDeclaration && !Line.InMacroBody);
       Contexts.back().IsExpression = OperatorCalledAsMemberFunction;

Yes, but it would break this test case: https://github.com/llvm/llvm-project/blob/e469d0d636f36140b08d0b5f603c043008307bcf/clang/unittests/Format/FormatTest.cpp#L11573

I understand it's a nasty workaround, though, but it's quick. The other option seems to be rewriting how overloaded operators are annotated to instead be more like regular function declarations, but I haven't gauged how hard that would be
