I think `CallDescription` can only identify objects/functions which has
`IdefntifyerInfo` in them. AFAIK operators don't have such. Though somehow AST
matchers of Clang Tidy were triggered with this:
`functionDecl(hasName("operator>>"))`
I'm afraid it needs to be a different patch to replace with
`CallDescriptionMap`, even though I agree with you.
