================
Comment at: docs/LanguageExtensions.rst:2349
+attribute is supported by the pragma by referring to the
+:doc:`individual documentation for that attribute <AttributeReference>`.

I agree with this idea, I think it would be useful to have the ability to specify the target declarations. I do think it would be better to use the 'clang attribute' umbrella pragma, and maybe add an extra argument to the 'push', e.g.:

```
#pragma attribute push (annotate("functions-only"), applicable_to=function) // or maybe received_by=?
#pragma attribute push (annotate("struct+enum"), applicable_to=struct, applicable_to=enum)
```
