I think you can do something like this:

  Finder->addMatcher(
      cxxOperatorCallExpr(
          hasOverloadedOperatorName("[]"),
          calle(cxxMethodDecl(ofClass(cxxRecordDecl(hasName("::std::array")).bind("type"))))
          hasArgument(1, expr().bind("index")))
          .bind("expr"),
      this);

In such case instead of checking argument passed to call, we check what operator we used and who provided it.
