--- Comment #9 from Harald van Dijk <harald at gigawatt dot nl> --- Oh, very sorry about that, I hadn't realised clang stopped using gas. clang uses its own assembler now, which supports quoted names this as a syntax extension. Now that there is a possible syntax already, perhaps that will be easier to bring to gas. gas does indeed seem to properly handle your suggestion of parenthesised identifiers on x86-64 already, even if they have names such as $0 (unlike clang's assembler, oddly). However, I do worry that this may be too brittle, because of other systems (even using gas) where $ is used more extensively in standard syntax, such as register names, where parentheses cannot be used to force interpretation as a symbol name because register names may also be parenthesised.
