Does this issue occur when all extensions are disabled?: Yes

brackets are punctuation when define function

brackets are meta when call the function

I test this basic code in other languages like golang, ruby. brackets are always punctuation instead of meta.

Should JS function bracket be meta instead of punctuation when calling the function?
