I get this error while running `ninja check-clang-unit`. My build tree is
configured with `-DCMAKE_CXX_COMPILER=/usr/bin/clang++` and
`-DLLVM_ENABLE_WERROR=On`.
By the way:
```
[](PrintingPolicy [[maybe_unused]] &Policy) { Policy.SuppressTagKeyword =
false; };
```
would result in:
```
clang/unittests/AST/DeclPrinterTest.cpp:1394:23: error: 'maybe_unused'
attribute cannot be applied to types
```
```
[[maybe_unused]] [](PrintingPolicy &Policy) { Policy.SuppressTagKeyword =
false; };
```
would result in:
```
clang/unittests/AST/DeclPrinterTest.cpp:1394:5: error: 'maybe_unused' attribute
cannot be applied to a statement
```
I don't know where to put `[[maybe_unused]]`.
